Introduction: How to Repair Your Boots Using Sugru

Picture of How to Repair Your Boots Using Sugru

Good boots just get better and better the more you use them and it's devastating when they start to fall apart, so it's great to find a way to keep them in service...

Sugru is great for fixing boots because:

- it bonds to most materials (including fabric and leather)
- is flexible when cured
- is waterproof

A perfect match for the great outdoors.

TIP 1: sugru is not suitable to repair your soles, we recommend that you use sugru for the uppers only.

TIP 2: sugru bonds to most but not all materials, we have seen people repair loads of different types of boots it is worth remembering that it might not bond to yours.

Step 1: Cracks and Leaks to Repair

Here are some parts of these amazing boots that we repaired before they got any worse

Step 2: Colour Matching

Picture of Colour Matching

Sugru comes in a number of colours (orange, blue, green, black and white) but you can also mix the colours to create a specific shade. This is super useful when you want to fix your favourite boots in the most discreet way possible.

With every multipack of sugru comes a mega helpful little booklet called '7 steps to becoming a sugru guru' and is filled with loads of awesome sugru tips. If you go to step 6 then there is a guide to help you mix your sugru colours.

Start by matching the closest colour on our chart to the colour of your boot.

I decided to go for 90% orange and 10% green. Take the percentage amounts of the minipacks and mix them together in your fingers until the colour is solid throughout.

You may need to add some smaller amounts of extra colours to achieve your specific shade. With this hack I had to add a bit more green and a little bit of black. When adding more colour do it in small amounts and constantly keep checking the colour against your boot. It is easier to keep adding small amounts until it is right than going too far and having to make up for it.

TOP TIP: When mixing sugru colours your fingers can become very sticky. Use dry tissue paper to clean excess sugru off your fingertips.

When mixing colours you may have a bit of sugru going spare, see steps 3 and 4 on tips of how to best make use of these bits.

Step 3: Applying Sugru to Your Boot

Once you have your colour ready it is time to apply the sugru to the damaged areas.

To begin with, if there is a large flap of fabric that is loose it could be a good idea to use a small piece of sugru to help hold the flap down.

When applying sugru to your boot work in smaller amounts, it is far more manageable.

Press and rub the sugru into the fabric of the boot. Start by creating a tin layer with a good bond and work on thickening it later.

If dealing with a piece of ripped or torn fabric it is best to work the sugru into the fabric either side of the tear first and then to bridge the gap with more sugru to really ensure that the join is secure.

If the sugru becomes hard handle while applying to the fabric it may be because you have too much sugru on your fingers. Again use dry tissue paper to remove excess sugru from your fingertips. Do this regularly to keep a clean hack.

If you are still having trouble then try using the back of your fingernail to spread the sugru, it seems to stick less.

Once your sugru is down smooth the hack by gently rubbing it with your fingertips.

Leave to cure for 24 hours before taking out and about.

Step 4: Fixing Frayed Laces

A common problem that comes with boots is the fraying of the lace ends. Small but annoying. Step in sugru. With those spare bits of sugru left over from the colour matching you could bolster up your laces and save yourself a lot of hassle.

Just roll a small piece of sugru around each lace end and leave to cure overnight.

TOP TIP: When leaving the laces to cure make sure that they are not touching any other part of the boot, you don't want them to bond together.

would this work on a pair of pony hair boots with a cracked seam?

kawaiilover (author)2014-03-01

This stuff is cool, its like super glue clay!

bakdrft (author)2014-01-03

THank you, Ill send you a PM

bakdrft (author)2014-01-01

I tried this stuff on a cracked sole. Did not work.........

projectsugru (author)bakdrft2014-01-01

Sugru is not suitable for using on the soles of footwear as it does not have good abrasion properties. If you private message me your address I'd like to send you some replacement sugru.

Best, James

My favorite boots are self destructing. The soles still have lots of wear left, but they've come loose from the boot in the front. I left them in my hot car for a few days and that apparently did in the glue. I tried some glue that professionals use, but I'm not one, and it didn't do the job. Will sugru work for them, or do you have any other suggestions? You did ask for more challenges 8-}
I love the colorful repairs!

bethelcobbler (author)Tinker L2011-12-02

Unfortunately, your car's heat activated the cement- which is why it's never a good idea to dry cemented shoes in a dryer. In some cases, by heating both the sole and upper surfaces, you might be able to reattach the sole (provided you do not have the glues from repair attempts covering over the original cements).

Using a heat gun that generates heat about 500 degrees, blowing the two surfaces for a few minutes might (again- might) make the cement tacky. If it does, you will need to press the sole to the uppers until it cools in a minute or two. pressing the shoe against a cushion will help to envelope the sole to press it securely against the uppers.

Neoprene cement, which you likely obtained doesn't work with a lot of synthetics like urethanes, vinyls and thermoplastic rubbers. It's designed for leather and friendlier synthetics. Probably that is why yours soles did not attach.

Although there are variety cements for a shoe repairman to use that would be effective- your best bet might be to use cyanoacrylate, or super glue along with an activator that forces it to dry instantly. You will find that it does take experience and caution to restore your soles. You might have to glue it in increments, not everything in one shot.

projectsugru (author)Tinker L2011-11-13

sounds like it's totally worth a try, hard to say without seeing them though. sugru is heat stable to 180ºC (356ºF) so you could leave them in your car no probs :)
Cheers for the challenge and the positive feedback

Nelyan (author)2011-11-12

Looks like I too need some sugru in my life. All of my good shoes have ripped from the edge of the sole from the ball of the foot becoming un-waterproof.

Æ (author)2011-11-11

Never heard of SUGRU until now. I've always used "Shoe GOO" to repair boots and shoes with great success.

capops (author)2011-11-10

There are a few home made alternatives to Sugru listed right here in Instructables...

srinivt (author)2011-11-08

Thanks for making this. I have a different problem with my shoe - one of the lace buckles is broken (see image). Any ideas on how to fix this?

Thank again!

bethelcobbler (author)srinivt2011-11-10

You might check out it is on page 40, the L-1223 Speed Lace, black. If you are able to somehow obtain one (Ohio Travel Bag's minimum order is $30- impractical for one tiny item) , use a pair of long nose pliers in between the "dee ring". As you pull the handles apart from each other, the dee ring joint will open up so that you can transfer it to your existing loop that is riveted on your boot. Just use caution while opening the ring, since going too far will distort the shape of the dee ring. With the aid of a pair of pliers, you can squeeze the ring back in place.

easy take a plug from your sink take the metal ring of the sink plug and then open up the triangle metal bit and replace it EASY and cost nearly nothing your friendly DEVIL

projectsugru (author)dmoloch2011-11-10

oooh, I like that idea, wish I though of it, very clever

joeofloath (author)srinivt2011-11-10

This happened to me, I sent the boots back to the manufacturer and they repaired them for me. Unfortunately the repair let water in, but sugru can fix that :D

projectsugru (author)srinivt2011-11-08

oooh, now that is a challenge !!!! These things take a lot of force and sugru would tear under the force. The only real solution is to switch it out, you can get these online, just google "boot eyelet" and you should find some or maybe even in a reapir shop might have them. Just rivet it in place...

You could still use sugru to make the repair waterproof again...
Hope this helps

srinivt (author)projectsugru2011-11-08

Thanks! I really appreciate your help.

projectsugru (author)srinivt2011-11-08

cool, my pleasure, more challenges please :)

olmon (author)2011-11-10

Something to think about - - I use the same basic method to repair air mattress leaks, but I found almost immediately that the repair needs something to reinforce it. ( I Use urethane gasket material in a tube from the Auto parts store.) Place some of the patching material on the surface & spread it for a short distance around the hole. Cut a piece of cloth that will fit slightly inside that area. Press the cloth into the repair material, then spread just enough more material to 'bury' the cloth. Let sit for 12+ hrs to cure before blowing up to use.

MrFixItGuy (author)2011-11-10

I can't seem to find the Sugru web site. Any suggestions?

projectsugru (author)MrFixItGuy2011-11-10

Hi, we launched a new site today, you might have tried when it was down. It's up and working great now - :)

Peale (author)2011-11-06

I've only heard of sugru recently; where do I get it?

gia (author)Peale2011-11-06

Peale, you can get sugru from or e.g. from Thinkgeek or some museums. is located in UK but the shipping worldwide is cheap as it's very light.
I've used sugru to fix a lot of plates and pots that had chips in them, and even a rusting hole on my bathtub. It works great for all sorts of repairs.

Peale (author)gia2011-11-06

Excellent! Thanks for the info.

Next question: what IS a suitable material for the soles? I have a great pair of boots that could benefit from both material and sole repair.

gia (author)Peale2011-11-06

I'd love to find something for the soles fix too. I walk too many shoes out. :)

will427 (author)gia2011-11-10

GIA, See my comment above about tennis balls and / or bicycle tire rubber with shoe goo.

will427 (author)Peale2011-11-10

I am a tennis player who has a bad ankle and as such wear out my shoes on the corner of the heel. I was buying new shoes every two weeks. A previous college player told me that his team cut up tennis balls and glued them to the sole. I tried and it works and the ball on the sole willl last surprizingly well.
I though that maybe tire rubber would be better and settled on bicycle tire. I went to my local bike shop and they gave me an old worn out tire. It is thin enough to easily cut with shears and it glues well with Shoe Goo. Give it a try.

jlewis5 (author)Peale2011-11-06

Look for a product called 'Shoe Goo'. Any shoe repair place should have it or something like it and most shoe stores should as well.

It's a fairly versatile material in itself and has a lot of uses.

DieCastoms (author)2011-11-10

In the final bits of Step 3, if you do not want such a shiny patch (You did say you were going for discrete), there are two things I can think of.

1. Have a scrap of leather of ANY size around. Once you have finished forming the patch where you need it and smoothed it out well, press the scrap of leather into the sugru firmly and evenly but not hard enough to displace any of it, and then peel it back off. This will leave a leather texture in the surface of the sugru and hopefully make it a little less conspicuous. This method will give the texture but might leave the sugru still a little more shiny than the rest of the boot.

2. Find some yarn that is the same color as your boot and with a SHARP pair of scissors, cut fibers from the end of the yard reducing it to the dustiest texture you can manage without cutting yourself. When your patch is done, dust the yarn fibers over the sugru and press them in JUST enough so they will stick and so you don't leave bumps or dents from your fingers. You may be able to find "flocking" materials if you have a large craft store in your area and not have to shred the yarn yourself. This method should take the shine out of the sugru but may not last as long as the other method, if the fibers are worn off.

Maybe the best solution would be a combination of both methods.

Hope this tip helps.

projectsugru (author)tonyscott2011-11-07

Hi tonyscott, sounds like you could definitely do with some sugru in your life. You can buy it online, at , enjoy!

crankyboy (author)2011-11-06

Sugru is great!Just don't try it on the bottom outsole of the shoe if you are going to use them on rough pavement.I tried myself and it didn't last long(couple of days) :( .Other than that and this thing is a modern miracle!

marycolletta (author)2011-11-06

So this product, Sugru, is only available on line or do the have it at any retail stores like home depot or bass pro shops or such?

iwoodinspire (author)2011-11-06

Have you taken them out and about yet? I tried to fix a crack in my boots with shoe goop one time, and it says it's flexible etc. But the first time I put them on it all separated and reopened again. I'm wondering if sugru can take the punishment.

canida (author)2011-11-06

This is excellent and timely! I have some boots in need of care, and was at a total loss - you've solved several problems for me at once. Not sure why I didn't immediately think of Sugru.

Thanks, guys!
