Before parting with your hard-earned cash, you should consider a couple of things. Firstly, like with clothing, fit is king. You’re not going to get the most out of your workout if you’re wearing a shoe that doesn’t fit properly.
Shoe sizes that work in different corridors of your life might not be appropriate in the workout or lifting arena. For example, if you’re lifting heavy weight you’ll want a wider shoe to ensure a more stable base and help transfer power.
Likewise, you don’t want to do CrossFit in a shoe that is too small and doesn’t allow maneuverability, or pound out cardio in sneakers that aren’t supremely comfortable and light.
