Shoe Of The Day: Nike Free 4.0 v2

The low-profile, Phylite midsole provides a resilient ride and is tough enough to double as an outsole, which has dramatically reduced the overall weight. www.nikerunning.com

With a newly constructed upper and modified arch designed to mimic barefoot running, the Free 4.0 has been updated with a seamless, sock-like fit that hugs the foot but still allows for easy on-and-off. www.nikerunning.com

Diagonal cuts throughout the arch enhance natural motion flexibility and help increase foot strength. www.nikerunning.com
