Look for shoes that are made specifically for running.
All sneakers are not created equal. According to Active.com, shoes made specifically for running are designed to handle the shock of 2.5 times your body weight. This kind of support protects your body from the stress inflicted in each stride, as running lends a repeated impact that differs from other activities.
Leave some wiggle room.
Even if a shoe seems to fit perfectly at the first try-on, for maximum comfort shoppers should look for a fit a bit bigger. SELF suggested that runners buy shoes that leave a half-inch (or a thumbnail's worth) of wiggle room between the end of the toe and the end of the shoe. "Pressure on the toe is never okay," said Kate Reese of Brooklyn Running Co. to the magazine. "If the fit is so constrictive that the toes can't move, you will most likely develop a blister during the course of the run. Any friction will certainly result in a blister that even the most technical sock can't combat."
Running shoes are for running, not running errands.
Wearing your running shoes around the house or to the grocery store may be convenient and comfortable, but this habit can change the way your shoes are worn in. According to Competitor.com, wearing running shoes for basic errands or chores can change the wear patterns on the outsoles, leaving you in need of a new pair of shoes much faster.
