Bad guys on the run, look out. The Telson GTX delivers athletic performance to experts unwilling to compromise support, stability and toughness. The key to achieving these benefits lies in the use of Danner's patent pending EXO™ support system. Instead of a rigid steel shank, the support system utilizes a lightweight exoskeleton chassis that provides toe- to- heel comfort while still improving flexibility and support. The result is a boot that's comfortable on the run, and tough enough to endure everything the street can throw at it.
