You really (really!) should wear socks
Now that your feet are clean, dry, and deodorized, you're mostly there -- but there's still the matter of smart footwear choices. When it comes to socks and foot odors, there are two things to bear in mind.
The first is to wear them. Donning a fresh pair of socks every day will go a long, long way in keeping your foot stench at bay. The second is to opt for socks made of natural fibers, like cotton or wool, avoiding synthetics and blends that don't breathe as well and can trap sweat.
Lastly, if you notice that your socks are retaining a foot-y smell even after laundering, try a sports detergent or use a half cup of white vinegar in the rinse cycle of the wash to deodorize them.
De-funk your shoes...
Of course, none of this -- not the clean feet, not the powders, not the perfect cotton socks, none of it -- means a thing if you're slipping your dogs into foul-smelling shoes. This is where odor-eliminating sprays, like Dr. Scholl's Odor-X Odor Fighting Spray Powder, come in. Give your favorite loafers, boots, or tennis shoes a good blast with one of these products and you should be good to go.
