This was a Christmas gift for our son-in-law.  He has taken up running and looked up information about barefoot shoes.  He was intrigued by the comparisons of this shoe with the barefoot runners around the world that are doing so well in marathons.  It took a little time to get used to the shoes, but he loves them. We live in Colorado and have had a lot of snow and ice on the ground.  That hasn't stopped him from running in these shoes. We purchased the shoes from Amazon.com and they arrived before Christmas in perfect shape.
