We've changed the bootie-game again with our Solite 2.0 technology. The 3mm Custom Pro 2.0 integrates our new 3-Point Strap with the 2.0 Sole for precision fit and instant response. We've also upped the warmth even more with our new metal-grid Thermal Rebound plush lining. Simply put, our Custom Pro 2.0 is the best watersports boot in the world. Full stop.
