The North Face Men's Ultra Guide (A4UM) is an off-road running shoe. CRADLE GUIDE technology provides impact control. The impact control allows the foot to strike the ground naturally. The North Face Men's Ultra Guide (A4UM) is covered with abrasion-resistant mesh. The Ultra Guide is breathable. For those who do not favor a Gore Tex shoe, this is the ticket. If they get wet, they dry fast, and if you have ever spent multiple days in the field, you know how important that is. The support provided by this shoe is more than enough for the roughest terrain. The North Face Men's Ultra Guide (A4UM) is meant to keep your feet happy throughout days of off-road punishment.
