Custom 5mm 39 / 7

Our Custom Series is simply the lightest, most barefoot-feeling boot we make. We cut no corners with the Custom, including triple-sealed seams, our exclusive EZ-O Cuff, and a new Tatex-Print heel spine. Combined with the precision fit of our custom heat-molding process, the Custom provides barefoot feel and response for every possible foot shape: high or low arch, narrow or wide width, high or low volume.

Updates to the 2021 Custom include:

Tatex-Print heel spine for improved durability and easy on-off. Double reinforced, extra-strength heel-loop for long-term durability. Now available in US Men 5/Women 6.5 (Black/Gray only) for the ladies and kids. Included Knit Heat-Booster Socks now come in three sizes for more precise fit. Small: 5-7; Medium: 8-10; Large: 11-13.

Recommended Water Temps: 7C+.

Sizing Tip: Order your regular shoe size or 1/2 size down. For example, if you are a size 10.5, order a 10. If you are a size 10, also order a 10. Women should order 1-1.5 sizes lower to convert from Men's sizing. So if you are a Women's 8, order a Men's 7. If you are a Women's 8.5, also order a Men's 7. NOTE: If your feet are exceptionally narrow or low volume, you may want to size down even more.
