Finding the right running shoes comes down to comfort. A shoe that’s too short or too narrow will squeeze your foot until it’s numb, and a shoe that’s too long or too wide will make you feel like you’re wearing flippers. So it’s important to find a shoe that fits properly.
The best way to find the right running shoe is to try them on first. Go into a store and lace the shoe up. Is it comfortable when you stand and walk? If it’s not, running will only make it worse.
Then check the length and width. You should have about a thumb’s width of space between your toe and the end of the shoe. Similarly, your feet should not be spilling over the side of the shoe; if they are, the shoes are too narrow.
