Built on TREK sport platform, the LONTRA model makes the experience fun and comfortable. A multi-layer laminate upper with fully taped seams provides insulation and water resistance. The micro pile fleece liner is soft against the skin while wicking perspiration away from the foot. Other features include: a neoprene heel cuff to keep out snow and debris, a reinforced hook and loop closure for a snug and secure fit; and reflective surfaces for safety at night. The 4mm EVA midsole provides insulation from frozen surfaces, and the Trek outsole provides traction, durability and superior plating protection.
