Not at all! The insole is not the same. I wear a size 6 in Vionic shoes, and I have several pairs. an excellent product, i bought 2 pairs, and ill probably buy 2 more. The part that flips open is amazing. These are comfortableI am glad I purchased these Had to replace my last shoe rack as my son thought it would be good to practice gymnastics on it. This shoe had way too much friction and discomfort that my feet started to bleed the first day of wearing them (the back of my heels/ankles), so that wasnt so great. Have not tested the battery life on this thing. dont tighten down the 4 large bolts all the way.
