These are rubber overshoes. They can be worn over riding boots. They are useful for tasks like washing horses. I have only used them once, but due to the material, fine wood shavings are difficult to remove. - Brand: NORTON - Type: Rubber Overshoes - Sole Design: Rubber sole (with anti-slip features) - Size: L (Usual shoe size 24.5 cm, Riding boot size 38-39) Thank you for looking.
