1, prepare a small watering can, and pour in 1 bottle cap laundry detergent and a small amount of alcohol. Shake the watering can up and down to mix the liquid evenly. Spray the prepared detergent on the dry towel, and then put the dry towel into the slippers.

2. Hit the surface of slippers with your fist, so that alcohol can fully absorb the sweat and odor in slippers. Finally, take out the towel and blow dry the inside of the slippers with a hair dryer.

Skills of choosing cotton shoes in winter

1. Fold the sole in half. The place where the shoe bends should be in the first third of the sole. A good sole should provide sufficient grip and flexibility, and it should have a hook center to support the middle position of the foot. If the middle is too soft, it means that this shoe has no hook and can't hold the arch when walking, which may easily lead to flat feet.

2. Pinch the top and heel of the shoe. These two parts need enough hardness to protect the soft toes and ankles. The top of the shoes should be very wide. Don't buy pointed shoes to avoid squeezing your toes. Keep your heels on both sides and don't bend too much.

Twist the shoes with both hands to see if the shoes will recover soon. Shoes need to have enough stability. First, check the quality. Second, give the soles of the feet a fixed protection. Otherwise, they may sprain or develop bad walking habits.

4. Put your hand into the forefoot of the shoe and press it. If it is too soft, it will affect the skin impression, especially the insole. This part should not be too sticky or too thin, otherwise it may make you clumsy or fall.
