These shoes are great for every day minimalist wear, but the seam in the toe is very bulky and is centered so that it rubs the front of the toe while running. I had blisters the size of quarters the first 3 miles, and had to take them off and limp home. I will never purchase another Zem. I suggest vibrams, you just can't get a better minimalist shoe than the vibram. They look funny, but are very functional.
