I LOVE these shoes, but they use a double stick tape to hold the two laminations of toe cover together. This tape quickly separates and balls up into a wad that annoys the hell out of me. I have 3 pairs of these and on all three, I've had to take an Xacto knife and surgically remove these annoying sticky balls from on top of my toe. Never had sticky balls on my toes before these shoes. Other than that, they rule.
