This should be common sense, but the first step in preventing rubbing (and the ensuing blisters) is picking shoes in the right size. “Women can be vain about sizes, even when it comes to shoe sizes,” says Yoshida. So even if you’re normally a seven, don’t worry about buying a pair in size eight if that’s what fits. On the flip side, don’t try to convince yourself a size eight fits just because the store is out of size sevens. If you’ve got bunions, opt for wide widths, or take them to a cobbler before wearing them to get them stretched. “They can put a little pocket in your shoe right where your bunion goes,” she says.
