The FREE 5.0 v4 is the 4th iteration of a terrific training tool. Splitting the difference between a traditional running shoe and being barefoot, the FREE 5.0 v4 allows runners to develop strength in their feet. Use it for warming up, cooling down, running drills and strides. Many runners will eventually log a good portion of their miles here as well. Also a great shoe to just wear around, as it is super comfortable and helps feet function better.
