Intro: Memory Foam Flip Flops
Flip flop paradise is just moments away.
I have always really liked playing with ear plugs. The foam they are made of is very similar to the stuff expensive memory foam beds are made out of.
Sandals seemed like a logical application.
You will need about 250 or so ear plugs and one pair of sandals sized 1 or 2 sizes too big.
Also, a hot glue gun, lots of glue, a knife, scissors and a pen. A pair of sandals that fits you is a good idea too.
Step 1: Trim the Sandals
Gluing the ear plugs to the foot bed of the sandals effectively shortens the straps, which is why I suggest buying some oversized flip flops and trimming them down.
I used a pair that was one size too big but I think two sizes bigger is a better choice.
Use a pair of flip flops that fits you well to trace the appropriate size onto the bottom of the oversized pair.
Use a sharp knife to cut off the excess parts. I tried to use scissors at first and it didn't work out too well. If you have a band saw this may be the best choice, but a knife works just fine.
Step 2: Arch Support
Draw a curve around the inside strap in the appropriate area for an arch support.
Now cover that area with ear plugs. Apply hot glue to the flat side of the ear plug and press down onto the foot bed. It is a good idea to do both sandals at the same time to keep a similar placement pattern going.
Step 3: Cut the Ear Plugs
In order to reduce the number of necessary material a bit, I cut the remainder of my ear plugs in half. Scissors work really well for this and you can cut two or three at once if you line them up right.
Step 4: Continue Gluing
Hot glue really is pretty great stuff. It is really quick and easy to use and adheres nicely to most foams and fabrics.
I tried to keep to a fairly consistent concentric pattern when gluing on the ear plugs. The outside layer is all the rounded tops of the ear plugs and then there is a layer of bottoms. The pattern fell apart a little towards the inside, but that's okay.
Step 5: Finish Gluing
When I started I was pretty sure that the giant pile of orange ear plugs I had would be enough, but I was wrong. I had to go on search for some more ear plugs and only found smaller yellow ones.
Since I had been working on both sandals at the same time there was a matching empty area and as a result now there is a matching yellow area. That was quite convenient.
Step 6: Walk on the Clouds
The only thing left to do is slip them on and enjoy the glorious comfort of memory foam on your feet.
As one might hope with ear plugs, there is also a sound dampening side effect.
