  • 5 out of 5 With these you feel like you are stepping into memory foam-oh wait its because you are. They have the best insoles which support my med-high arches without the need of bulky inserts. I run like 15-20 miles per week and these really have been a godsend compared to my last shoe. I definitely recommend these asics especially for those who overprinted becuase they give great support!
