Men's BILLY Fit Adjustability Spacers

At BILLY Footwear, we know that no two feet are exactly alike—and that’s why we’ve designed our shoes to allow depth adjustment fitting spacers to help you achieve a truly customized, pressure-free fit. Whether you’re accommodating unique foot shapes or making room for medical inserts, our system includes two EVA foam spacers—one 1/16" and one 1/8"—that can be placed under the insole to fine-tune the interior volume and depth of each shoe. It’s all about giving you the flexibility to dial in the fit that feels just right for your feet, so you can step into comfort with confidence, every time.
