How to Repair Your Boots Using Sugru




About: The team behind Sugru, the mouldable glue that makes fixing and making easy and fun. Do-ers of the world it's time to get excited.

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

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.

    Question 4 months ago

    I've bought sugru to repair a boot which has separated from its sole at the heel. Can I use sugru for this?

    I have a pair of Columbia boots, like new, except the rubber sides are dried, cracked, and/or separating from the leather quarters. Can sugru help with this? See photos.

    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.

    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!

    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.

    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

    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.

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

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


    7 years ago on Introduction

    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!

    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

    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


    Reply 7 years ago on Introduction

    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
