This is a super plush, comfortable shoe that you can wear for long sessions. The Evolv Defy benefits from an easy on/off velcro fastening that is uber comfortable with it's plush padded lining and relaxed tension heel rand. What makes the DEFY even more attractive than it's sleek sexy look, is that they perform better than most all around shoes due to the vegan friendly synthetic uppers that don't stretch out. These shoes are as sensitive and soft like a slipper but with the security of velcro.
