PREVENT FALLING: The socks can prevent falls on slippery wood and stone floors. The grip is perfect for keeping you steady without having to wear heavy house slippers. The grip material is undecteable, you won't feel odd stepping on them. These non skid socks have plenty of cushion, you can't feel the grippy spots on the bottom when you are standing on tile surfaces, unlike other grip socks that make you feel like you are stepping on weird lumps.

Non skid socks with open top design easily conduct the sweat and moisture out, increase the breathability and help on repelling sweat and reducing odor, so that you feel comfortable all the day. MATERIAL: Made of Cotton. Premium cotton keeps your feet comfortable fit. Easy to care for non skid socks.
