These are the original Newton minimalist running shoes.  The shoe truly wraps around your feet.  I have high arches…and can immediately see the buildup of the muscle structure needed to support the arch.  With this shoe your feet dictate how you run…unlike other running shoes including the newer versions of Gravity with anti-pronation sensor and wide platform.  Newton really needs to bring this style back.  I tried their Gravity III and this was a really big disappointment.
