The four-season, waterproof shoe designed to adapt to your long training and adventure runs over mud, roots, and rocks no matter the forecast. The spacious forefoot and secure midfoot hold deliver comfort and stability, the mud-releasing lug pattern gives you the control to rip and grip across any terrain, and the durable upper and VibramA(R) Megagrip outsole stand up to unforgiving rock and soggy trails. Size and fit tip: We&';ve heard that this product runs large. Please refer to the sizing chart to find your foot length, then we recommend choosing a half size down. Need a non-waterproof version? Try the Norvan LD 4 Shoe. Product tip: This shoe is designed for a Comfort Fit, giving you the most space at the toe and a less snug fit around the foot.
