<p>I currently use La Sportiva WildCat Trail Running Shoes size 43 for trail running/light hiking and Nepal EVO's size 44 for Ice Climbing and Alpine adventures. The Nepal EVO's fit me perfectly with a good midweight sock and using their additional tongue for the left foot which is slightly smaller than my right.</p> <p>I am looking at purchasing La Sportiva Olympus Mons EVO's for high altitude such as Denali and other real cold expedition type adventures that require a double boot. </p> <p>My question is how much larger do I size them to accommodate for the swelling of the feet at high altitude? Would one full size be ok? I am thinking a half size for thicker sock+ sock liner and a half size for the swelling of the foot, is this accurate or should I be sizing up even larger?</p>
