Thank you for viewing! This is an aftermarket boot zipper with 7 holes. As shown in the example photo, threading the laces allows you to put on and take off your shoes by zipping and unzipping. This product is perfect for those who find it troublesome to take their boots on and off, or who want to speed up the process. ☆ The zipper has an auto-lock mechanism, so it won't easily come down. ※ If you use boots for work or mountain climbing, it is recommended to tie the laces tightly to ensure the shoes function properly, so it is best to avoid using this product. Please note that this product is not suitable for those who use boots as tools. ※ Please use this product only as a fashion accessory or to assist with putting on and taking off your boots.
