Clean them every time you put them on, and every time you take them off. Tie the laces slowly and carefully each time you put them on keeping them straight. Never bend the heel down when putting them on, gently loosen the laces enough to get your foot inside with ease, using your thumb as a shoe horn. When you take them off, gently place the laces inside the shoe. Don't wad them up, and don't ever let them touch the floor. Oh, and always wear clean socks.
