I tried using it on several different bike shoes to build up the sole where it was worn down. BUT, once I had to get out a utility knife and remove some of the new sole material that I had added because that was how I learned that part of the shoe sole directly contacts the pedal on SPD cleats. And by making the sole thicker, it was much harder to engage the cleat.
Alternatively you could have lowered the cleat with a washer or two. I had the same when adding a stick on sole to a pair of SPD shoes, went to a lot of trouble to get it right then they spit elsewhere a couple of months later...
Adding washers is a good idea. I had not thought of that. Thanks.
