Features Teko's new strike-zone cushioning. Dense terry cushion in the heel and ball of the foot to reduce impact, but lighter cushion in the arch allows for breathability and better shoe fit. Waffle-knit zones provide greater stretch for an improved fit that moves when you do. Strategically placed vapor channels along the sides are flat-knitted into the design, creating a space for hot, sweaty air to escape. The result ... a cooler, dryer, and more comfortable foot. Teko's seamless flat-knit toe is knitted closed, never sewn. There are no lumps, bumps, or ridges against your toes. This prevents blisters and chafing. High needle count delivers the outstanding durability that Teko lovers have come to expect.
