O'NeillPsycho Tech 3/2mm St Boot

Flexible warmth in cold-water surf.

Made of O'Neill's advanced TechnoButter 2 neoprene, the O'Neill Psycho Tech 3/2mm St Boot protects your feet from cold-water surf while enhancing flexibility for sure-footed grip on your board. Its Minimal Seam Design promotes unrestricted mobility, with a Deep Split Toe for improved balance. External Fluid Seam Welds and Interior Taped Seams keep cold water from seeping through while the Anti-Flush Shin Strap keeps surf spray and water from leaking through the top. Plus, there's a heel-pull tab to prevent you from struggling when you're taking them on and off.

  • Familiarity: I've put it through the wringer

comfortable and sturdy. I have used these a lot and they still look great. I like a thinner booty, something just to protect my feet on the way out/back in and to take the bite off the cold water. These do that just fine.
