XSTANCE fits comfortably into sneakers, work boots, walking shoes, and most casual footwear. There's no need to size up, even if the insoles look a bit thick at first glance.
For the best fit, remove your shoe's original insole first and replace it with XSTANCE. The insoles add some height underfoot, so swapping (rather than stacking) keeps plenty of room for your feet.
Wide feet: XSTANCE works in standard and wide shoes up to size 2E. If you wear extra-wide footwear (beyond 2E), our insoles will likely run too narrow for a comfortable fit.
