I read the reviews and most said order a half size smaller so I did that and they fit perfectly with minimum slippage. Plus they ar Super lightweight. Weighting about 9 1/2 ounces for both shoes. The Goga Mat Technology Cushioning Is firmer, bouncier and more responsive than memory foam. Theyre walking shoes that feel like nice slippers. Its only the first day, Ill let you know more after a couple weeks and let you know how they hold up.
