Created for off-road, endurance trails, ultra marathon competitions and long training sessions.The extremely breathable Air-mesh uppers are mounted on a soft EVA graded platform (wider at the toe and lower at the heel) for optimum shock absorption in any condition and reduction of the ramp angle. The integrated lacing system uses a strap sewn to an internal stretch fabric with high frequency reinforcements on the external mesh. This allows greater versatility in boot tension throughout the boot, thereby enhancing comfort levels. Ultra Raptor unites the performance advantages of a snug-fit construction method with those of the comfort derived from the wider shape and sole. The result is a product that can be used for several hours and is the ideal choice for endurance trails and all types of off road trails.
