- New Upper Tech: A seamless, ultra-thin upper material called NanoPly covers most of the stretch mesh upper, providing additional structure in key areas.
- More Flex: Even though the v4 has tighter gaps between the siping of its platform, it improves on the flexibility of the prior Free 3.0 with the addition of a Transtarsal Flex Groove that runs the length of the shoe.
- Lower Drop: Nike lowered the heel-to-toe drop of the Free 3.0 v4 by raising up the forefoot stack height by 3mm.
The Free 3.0 v4 continues in the tradition of the Free series to provide outstanding flexibility that lets your foot move naturally. But don’t confuse this with a near-barefoot shoe – all of our testers reported feeling fairly separated from the ground in this Nike. That’s a benefit if you want to save your feet from the grit, grime and other hazards the roads have to offer.
The flatter platform of the Free 3.0 v4 helps mid and forefoot strikers get into their groove a little better, but since Nike did not lower the heel stack height, testers found the shoe to work just as well as prior models for heel strikers. No matter how they landed, testers appreciated the very linear progression to toe-off.
The more streamlined look of the Free 3.0 v4 carries through to the fit of the upper. The shoe doesn’t give your foot a whole lot of wiggle room. The snug fit contrasts a bit from the Free 3.0 v3, which had a more stretchy upper material that felt close but never constricting. Testers liked the look of the NanoPly overlay, but for the most part wished for a bit less structure, particularly in the forefoot at the base of the laces. The shoe also feels more anchored in place in the heel than the prior version. Overall, the fit is a good match for runners with narrow, low-volume feet.
“Amazingly lightweight and pretty responsive for a mid or forefoot strike.” – Lindsay
“It’s definitely not a barefoot experience, but the degree of flexibility and softness is hard to beat.” – Matt
“Imagine a sock with padding on the bottom and you have the Free 3.0 v4. The NanoPly allows varying degrees of flexibility and structure in the upper.” – Jonathan
