The Nike Free Powerlines II are the sum total of the brand's extensive experimentation with the innovative Free sole. Its pretty much the most advanced silhouette that's ever used the Free sole unit but somehow it seems to boast a sense of minimalism at the same time. In combination with a fully breathable suede upper they also feature nonrestrictive wires that gently support the foot increasing comfort & decreasing the chance of abrasion. This particular colour way makes use of a premium suede with a vibrant pink lining that also extends to the heel pull.
