I'm no runner - yet. I started wearing these shoes after years of trying to fight arch / lower back pain with the typical massage / taping techniques / arch support shoes etc. After doing a great deal of research on information graciously donated by the running community I decided to try something completely different and see what this barefoot business is all about. I found these shoes at my local MEC and I've been in love ever since. The feeling that the bottoms of my feet were ripping open with every step stopped within hours of wearing these shoes. Within one week all of my arch / back pain had vanished. 6 months later and it's still gone. I'm starting to think that maybe - just maybe - all those barefoot runners out there actually know exactly what they're talking about when they recommend this style of shoe. Hopefully one day soon I'll be able to say that I'm one of them. There is a downside to these shoes - if you can call it that. Once you start wearing 0 drop shoes there is NO going back! If I put on anything with even the slightest heel I feel my back pain returning within 30 minutes of wear. Thankfully Merrell offers several selections for casual barefoot shoes which has me covered at work / on the town however the options for mens foot wear that can stand up to a Canadian winter (if they even exist) seem to be eluding me. Dear Merrell - I'm hooked! Please expand your barefoot / 0 drop selection to winter shoes / boots.
