I have been in zero drop shoes for a few years now. I started in Vibram 5 finger and have tried a few in between. The thing I like about these over some of the others is the amount of cushion. I am 6'3 190 lbs so I need some cushioning. When I started running I started out in asics and was continually getting pains in my knees and ankles. I tried new balance hoping they would ease the issues, but no dice. When I finally made the switch to minimal/zero drop I noticed the pain going away, but did not like the feel of stepping on a little pebble and feeling like someone stabbed me in the foot. I switched from five finger to merrell bare access. They were almost perfect for me because of the light weight and comfort they had. But occasionally I would still feel the rocks stabbing my feet. I have a vivid memory of a rock about 10 miles into a half marathon that caused pain for the final 3 miles. I just got these and as soon as I did I went for a run. After about a mile to a mile and a half they felt like they had broke in and the stiffness went away. I ran on some gravel and in areas that I know have little sharp rocks to see if I could feel them in my feet. I didn't feel a thing. My only question is what is the deal with the little thing hanging down in the top front of the toe box? I don't notice it while running but when I took them out of the box and put them on I felt something there.

They took care of all of the issues I had with the previous version of the Sum 3. I no longer get that annoying Achilles rub and the fit was comfortable and the shoe was easy to get on in transitions for triathlons. I would buy these again, but would not buy the previous version again.
