No need to put them in a shoe bag, just clip them on for easy carrying. Since you don't put them in a bag, they are well-ventilated and may prevent odors? Suitable for any shoes, regardless of sport or purpose. With a carabiner, you can hang them on your bag or backpack for transport. They are useful not only for sports but also in various situations such as school and the gym. For soccer and baseball cleats, basketball shoes, volleyball shoes, running shoes, hiking boots, and more! The part that touches the shoes is made of soft rubber, so it's less likely to scratch or leave marks. The shoes didn't come off when I swung them around, but there is a possibility of them falling off, so please be careful. Clitch??
