The North Face Summit VECTIV Sky Women's Trail Running Shoes Part of TNF's pinnacle boundary-pushing Summit Series, the Summit VECTIV Sky Trail Running Shoes are their lightest iteration yet. Breathable Upper Supplying your feet with protection and comfort, the VECTIV Sky Trail Running Shoes have a breathable, protective upper. The materials shield feet from knocks and bumps on the trail, whilst ensuring a constant supply of airflow enters the shoes to keep your feet feeling fresh and comfortable during intense trail running sessions. Utilising a sock-like fit, and a precise foothold, the shoes have a precision fit last, for high performance on technical terrain. Working alongside this, the shoes have a traditional lace-up system, providing you with a locked-in fit and preventing in-shoe slippage from occurring.
