While many waterproof trail running shoes emphasize weather protection Montrail's Hurricane Ridge XCR takes comfort a step further with optimal breathability through a lightweight double-ply Gore-Tex® XCR lining. Above the lining you'll also find a special Stretch-Fit GTX® tongue that eliminates the pressure usually encountered by conventional folded gusset tongues. The dual density midsole features medial posting for pronation control--something you and possibly your orthopedic surgeon will appreciate after extended runs.
