Sneaker Care 101: How to Keep Your Kicks Looking Fresh

A brush, some patience and a second pair — the habits that keep a sneaker white.
Brush, don't soak
A soft brush and a little soap on the midsole; a dry brush for suede. Never the washing machine.
Let them dry slowly
Stuff them with paper and leave them out of the sun. Heat warps the sole.
Rotate
Two pairs worn on alternate days last longer than three pairs worn to death one at a time.
