Customer Reviews

Comments: so far i like them a lot. i had hope to be running more in them by now but i also got a blister on the top of my right big toe. I also got a small blister under the ball of my foot one week later. i hope to slowly reintroduce them into my runs in the upcoming weeks. Currently only about 20 miles per week after suffering 3 fractures in my pelvis in the summer.

Comments: My first pair of Newtons. So far I have no complaints and I love them. I've actually been wearing these for most of my runs since I bought them. Other than a small hot spot on the top of my big toe, they fit like a glove and haven't given me any blisters. I've been wearing zero drop shoes for a few years now and the forefoot lugs are hardly noticeable. They feel fast and slip on/off quickly. I can't wait to use these in my next tri in a few weeks...they'll definitely save me time in transition. Kudos, Newton! 5'9", 145 lbs, 30-40 mpw
