I wish I had taken the negative reviews on this shoe style more seriously. The size fit is terrible! Order 1 full size larger than what you normally do...also the Goga Mat technology gets tiresome on your feet after about a hour or less (That's if you can tolerate the floaty - not stable feel to them)  With the price I paid for these over priced sneakers I was expecting a awesome walking shoe - when in fact after 2 walks - I realized I got ripped off. There's NO ankle/arch support which I found out is a necessity for long walks. I even took out the special Goga Mat insoles & put in thin insoles and the sneakers are still too bouncy for my feet. Take my advice - don't waste your $$$ on these....go search for some REAL walking shoes!
