I spent quite some time researching these shoes, since to be honest, I was a huge skeptic with regards to the whole barefoot experience. I finally decide to take the leap and purchase these. I quickly realized how I couldn't have been any more wrong and I should've gotten these a long time ago. After any strenuous activity/workouts, my feet and knees have always been sore later during the evening or when I get up in the morning. I have always attributed this to the years of abuse to my legs from soccer, rugby and roller blading. I've used different types of athletic/cross training shoes and have spent a small fortune on them over the years with little to no effect on the soreness I experienced eventually. After the first few days, I immediately noticed that I slowly stopped having feet/knee pains in the morning. After the first week, I had no pain anymore and can now workout harder, faster and longer than I ever. I recommend this to anyone who has constant feet and knee pains. I hope Merrell continues to make these available in wide size and I know that I will never switch to anything else going forward. I am looking forward to a more fun filled and healthier summer! I have even convinced my wife to buy a pair and she loves it just as much as I do! My advice to anyone even considering the barefoot line of shoes. Just do it! Stop spending time researching and get these right away! You will love it.
