Furthermore reports taking your running shoes off while they’re tied speeds up the wear and tear.

“Slipping your sneakers off instead of untying the laces puts undue stress and strain on the heel counter, causing deformation and breakdown of the shoe’s material. The habit also stretches this part of the shoe, compromising fit and comfort,” explained Rock G. Positano, DPM, MSc, MPH, DSc (Hon), director of the Non-surgical Foot and Ankle Service at HSS.

“You can make your running shoes last 10 to 15 percent longer by untying them before taking them off. Once you've logged 300 miles in them or the treads wear down—or worse, you feel pain in your heels, knees, or lower back while running—you’re due for a new pair,” said Dr. Positano.
