I went on a trip where i walked many many miles a day (5-10) and forgot my walking shoes. I had flip flops or heels! So i went bought a pair of these. Wore them out of the store and for the rest of that day and the rest of my trip. No blisters, hot spots, or anything. i wore them barefoot as recommended. It takes a bit of getting used to the barefoot feel, but they are amazing! This is the second pair i order because i like them that much! I have worn them with socks, but much prefer them without.
