Psychotech 5mm RT Boot

Keep your feet warm when paddling out on chilly days with the O'Neill Psychotech 5mm RT Boot. Made with Technobutter 3 and Technobutter 3X neoprene, the bootie hugs your foot and ankle allowing for a responsive fit that doesn't restrict mobility. The 5mm thickness and taped seams work together to block out water while still holding warmth, so you can enjoy the waves when the water is down to 44 degrees Fahrenheit. The sole is also fitted with a grippy texture so you can keep traction on your board as you catch wave after wave.

  • Technobutter 3 and 3X provide easy mobility in the boot
  • Surf in cooler water down to temperatures to 44 degrees Fahrenheit
  • Hook-and-loop strap on shin and arch keeps a snug fit while surfing

Warmest Boots Ever, Minor Disappointment

I've put it through the wringer
Size Bought:
6' 4"

These boots have been exactly what I needed to help me get through the cold New Jersey winters we get out here! I purchased them at the beginning of the winter season and must have logged well over 30 days with them just up until the water recently rose above 56 degrees (F). They hold water well, the grip on my board has been great, the velcro has held up fine, and the overall boot has not begun to leak or wear out. My only disappointment and reason why I can't give these the 5 stars they deserve is because the inner lining of the boot has begun to rip and some sand actually managed to get under the lining, as you can see in the photo. It is nothing that has resulted in water leaking in, or lack of grip while surfing, or even an uncomfortable wear. However, because I did opt to spend the extra money for the Psychotech models I was hoping to have received a slightly better quality that would hold up a little better. That aside I feel that I will still be able to get a solid 2-3 more winter seasons out of these with some minor repairs to that lining and honestly when these do go I will most likely get another pair.
