I am 70lbs into a 140lbs weight loss and needed a pair of shoes to take me from walking to running. I'm up to a 17 min mile and these give me a lot of space around the ankle and are very light weight. My walking shoes were so heavy. I never got a blister or really had to break them in. They still manage to be supportive. I have high arches and while I don't feel super support in the arches, I don't feel like I have any pain like I do with so many shoes. They just feel great for the hour or hour plus I am on the treadmill.
