Take this advice and run with it: The National Park Service is warning travelers to the Grand Canyon that it’s so hot there this week, even your shoes might turn on you. In a tweet sent Monday, the Grand Canyon branch of the NPS shared a photograph of some well-worn shoes with the soles peeling away.
“Grand Canyon is an unforgiving environment,” the tweet warned. “The heat inside the canyon can cause shoes to come apart and heavy hiking boots can trap sweat and lead to painful blisters. Before setting off on a hike, understand the limitations of yourself and your gear.”
