Ever shave 🪒 your excess feet skin before they become calloused? With zero drop wide toebox shoes, I end up having thicker skin (from not ever shaving my feet for at least three decades) on my feet soles and around the sides of my feet. I've shaved off like at least a good centimeter or so of skin around the skin beneath and below where the pinky toe begins, after noticing that there was friction there but I didn't feel much of it yet felt like something was attached there. It wasn't a callus but it was thick enough to be a concern.
