Use of snowshoes are recommended. Individuals may find that boots and shoes are adequate for support and traction on cold, well-packed snowshoe trails. As the snow warms during the day, it may loose strength and individuals in boots and shoes may begin to post-hole, suddenly plunging knee deep into the snow. This can be hazardous for oneself and the post-holes can be hazardous for others. Even on cold days, post-holing is possible adjacent to the packed trail and could result in injury due to hazards hidden beneath the snow. Individuals in boots and shoes may also find it difficult to move off the trail in deep snow when passing others.
