Nike Free sneakers have that appeal of being completely stripped down to the bone. While it may certainly feel that way, there’s actually a ton of research and performance tech that goes into the Free models – particularly the newly released Nike Free Haven 3.0. The upper is completely seamless, but offers freedom and restriction of movement at the just the right areas – the midfoot, for examples, features larger tesselation cut-outs for improved torsional flexion of that area. Dynamic Fit construction also wraps the fore-foot for a glove-like fit, while a sturdy rear cradles the heel for supreme stability. The Free Haven 3.0 is available at retailers now, so take a look at the gallery below and get your summer training in full effect with this top-of-the-line training shoe.
