I’m a big fan of a proper lifting shoe. A flat sole and proper arch and ankle support make a difference, especially when you’re performing heavy squats and deadlifts.
For almost two years I lifted in the New Balance MX20 Minimus and loved it, but I’ve found something I like even more: the INOV-8 BARE XF 210.
This is hands down the most comfortable training shoe I’ve ever worn. It weighs almost nothing, fits snugly but not too tight, has a perfectly flat sole, and has great arch support.
