Danner's Telson Side Zip GTX incorporates a quick and easy on-and-off feature for elite law enforcers. A durable boot on the job, the Telson incorporates a side-zip option. The contoured zipper accommodates the natural design of both the boot and foot for a precise fit. In addition, the Telson features the Danner lace-to-toe system for added stability. Telson's EXO platform eliminates the standard shank system used in conventional boots and replaces it with a light TPU exoskeleton chassis. Therefore, the platform reduces weight, increases support and provides toe-to-heel flexibility. The Telson Side Zip GTX is available in men's sizes 7 to 15 D, 8 to 14 EE (with half sizes to 12). The Telson GTX Series is also offered in the traditional lace-to-toe system in 6 and 8-inch options for men, and a 7-inch style for women.
