This is a replacement for the crocodile-style buckle on shoes. It includes two parts, one male and one female. It's very suitable for my men's size 10 crocodile shoes, and I hope it will also work for you. Just print out these two parts. Place the female part on the outside of the shoe and the male part on the inside. Press the two parts together firmly, and your shoelace should be secured. Now you can choose between a sport mode or a comfort mode. If you find this part useful, please give it a thumbs-up and share it
