I didn't decide to make this instructable until after I'd done the deed, so there will be missing photos.
My shoes are made so that they eat away at the insole where the ball of the foot is (look at the 3rd picture, they're like rubber knives). I wanted to fix this as quickly and cheaply as possible, and reinforce it so that it didn't happen again for a long time.
- Cutting knife/scissors
- Replacement insole (I used the insoles from some old shoes that are going in the bin)
- About 3 minutes spare
Step 1: Cut Off the Bottom of the Insole and Use It As a Guide
Just realised this isn't very clear.
So cut off the bottom half of your troublesome insole (top right in the image). Place that over the top of the rest of the insole (anywhere will do). Cut around it.
Step 2: Put in the Shoe
This is the 'reinforcement' part.
Step 3: Put in the New Insole
Hopefully this should last a while.
