Lastly, there’s always the old standby of bandaids, as well antiperspirant, Cunha tells mbg. Applying antiperspirant to the feet will help prevent sweating that can lead to friction (and subsequently, blisters), he explains. And of course, bandaids can cushion blisters should they arise.
Just remember, Cunha adds, this is more of a last-ditch effort option if you really need it. If your shoes are continuously causing problems after you’ve been wearing them for a while, they might not be the right fit.
