Even though I had to return this shoe, it is a perfect comfortable walking shoe. When I tried it on, my first thought was finally a shoe with a deep toe box. However, the arch support is high, too high for my underpronator foot. A high instep, allows the foot to roll to the outsole. Underpronators already walk on the outsole of their feet, so that makes this shoe wrong for underpronators, and perfect for Overpronators (people who walk on the inside of their soles). This shoe is heavenly for the right type of foot, and deserves it's 5 star rating. I should have noticed that it has SL-2 last before trying it on. Thank you Amazon Prime for your free returns!
