This is a customized remix of Brad2586’s Croc Heel Strap Button design. While his original version works flawlessly, I noticed a bit of discomfort on the inside of the button—likely due to the squared edge combined with my wider feet. So, I reworked the model to improve comfort by adding a beveled face to the inner button surface. I also beveled the tip of the male connector to make assembly smoother, though it still maintains a snug, secure fit.

The set includes two components: a male and a female connector. I tested it on my men's size 13 Crocs and it fit perfectly—hopefully it works just as well for you.

Installation is simple:

• Print both parts
• Place the female piece on the outside of the shoe
• Position the male piece on the inside
• Press them together firmly until they snap into place

Once installed, your strap will be secure and ready to toggle between comfort mode and sport mode with ease.
