The concept of custom 3D-printed shoes for every foot is intriguing, but these are not very good shoes. It’s difficult to put them on without your socks bunching up in a few places, and you will feel those places. Also the interior surface is rough and you’ll feel it through your socks. Your shoes will make a loud zipping noise when they rub against each other (or other items). It’s possible these issues could be mitgated with finer layer lines (these are printed much coarser than your typical 3D print).
They do offer good “squish” under your feet like gel soles, but it doesn’t outweigh the inside surface feeling like sandpaper. I can’t recommend these shoes, especially not for the price.
