Amazing Pair of Shoes

These shoes have changed my life. I have arthritis in one of my feet due to breaking a metatarsal in my 20's (I'm now 49), so have been unable to run regularly. I bought these in an effort to change my feet and body posture after reading Mark Sisson's book on primal living, where he advocates being barefoot as often as possible. This morning, I wore them to the gym and shot hoops in them, lifted weights, and then went to the park, took them off, sprinted barefoot, then put them back on. I love these shoes and have worn them every day since I bought them. I also have a pair of New Balance Minimus's, which I thought were great, but I haven't worn them once since I received these. I've also had several compliments on them because they look slick. They're also incredibly well made and sturdy, easy to clean and stay looking good for a long time. I'm about to buy a pair of the Cobi II's also, and would buy others if they were available in my size (why aren't they?). Anyway. I don't think I'll wear anything else as long as this company keeps making shoes. I recommend them wholeheartedly, and have texted the url to many people I know doing just that. I almost can't wait until they start looking worn, so I can buy a new pair and wear the current ones doing yard work, painting, etc.

bad blisters

This gave me terrible blister on my heel... would absolutely not recommend. The primus lux shoes on the other hand are the most comfortable shoes ive ever worn, get those instead

Hubby loves them!
