Pair of Keens trail shoes wore out, the heel tread worn down on one side.
I was wondering if I could add new tread?
Went into a bike store, asked for a big discarded tire. They found me a huge 27.5 x 4 e-bike tire.
Took it home, cut the remaining tread off my shoe heels, scrubbed them clean, slopped a layer of contact cement on, let it get tacky, then clamped on cut-to-shape bike tire sections.
Going to fill the gaps with black Shoe Goo glue.
Will it hold? We'll see!
