Just today, I declined to get $300 orthopedic inserts to correct the problem. In the field, we are seeing 3-4 years of service before needing a replacement, which for the money is amazing. Ill agree with other reviews that the adjustable part of this shoe seems pretty underwhelming but lucky for me no adjusting was needed. I guess they rushed them to market to get them included in the backpacker magazines best sandal award. the quality is terrible, it?s separated so the cover is its own piece and the bottom is it?s own piece, also it does not glow in the dark, i got the neon green one and white one because they both are suppose to glow in the dark and none of them do. 5 and even her flat tennis shoes were to big for this - complete waste. E contentissima e, detto da lei, sono comodissime. These were pretty hard to wear when I first had them because of the chafing on the inner foot they caused but I couldn?t bring myself to return them because of how comfortable they were despite it. It was a really good starter kit. Also, the item runs really small if you can get it in it helps you sweat, but honestly the waist band I was using made me sweat more.
