In all the years I trained for sport (I represented South Africa in Judo) I have never had such comfortable and responsive trainers, I really feel like I have been missing something. They have been designed to offer the most natural fit I have felt and it does feel like your running barefoot but with cushioning and flexibility. The flex grooves along the sole allow the foot to move in any direction and improve balance and it also has no-sew construction for even more comfort. I have road and gym tested these and I highly recommend them.
Please note I have not been paid to do this review, this is my opinion and I always strive to do honest reviews.
