Athletic garment developer Zensah is debuting its anti-blister running apparel at the 2005 LaSalle Bank Chicago Marathon taking place on 9 October.

The performance apparel contains double-sided moisture wicking Zensah fabric and is designed to eliminate chafing by being seamless.

Running apparel generally becomes abrasive when running long distances, causing blisters and chafing in the groin and chest area.
