A superbly built mountaineering boot for guides that are extremely tough on their boots or those that routinely travel in brutally rugged terrain. The Kenetrek Mountain Guide has many of the same features of the very popular Mountain Extreme boots with the addition of a stiffer midsole combined with the highly durable Kenetrek K-73 outsole. The Leather uppers are the same full 2.8mm leather for durability and moisture protection. The same waterproof and breathable Windtex membrane and 400 grams of Thinsulate Insulation keep you warm and dry no matter what the weather is like. Even with all of this support and durability, the Guide will still surprise you with a level of comfort unavailable ... until now!
