Customer Reviews

Comments: After 20 + years in the air pegasus, I wanted to try something lighter. I got these about 2 months ago and so far they have been very good. They are very light compared to pegasus but still have good cushioning, feels like a nice pair of socks. When they arrived I realized they were a half size to small. The return to running warehouse was very easy and had the correct size shoe in 4 days. (Didnt get charged shipping on return either)

Comments: Great shoe. I like the full contact sole. Very light and low profile. I rotate between these on the Mizuno Precision.
From: James, Bucktown, Pa

Comments: Really impressed with the shoe. Light and comfortable. Lots of room in toe box. Perfect for a light runner. First pair of K-Swiss and certainly not my last.
