X-Large (XL): Fits OMS Drysuit SuperFlex Boots (LG–XXL) or DUI RockBoots (Sizes 10–12). XX-Large (XXL): Fits OMS Drysuit SuperFlex Boots (XXL–3XL) or DUI RockBoots (Sizes 13–15). Sizing Note: If your shoe size falls right on the border, or if you wear thick rock boots or heavy drysuit socks, it's usually best to size up to ensure the foot pocket isn't too tight.
