Just wow!

"After having my 3 year old O'neill 4/3 Mutant with the detachable hood disintegrate around me a few weeks ago, I was skeptical to purchase another O'neill product. Low and behold my local shop only stocks O'neill, and with swell quickly approaching and my booties on the lam, my hand was forced to pull out the old credit card drop ~$145 with tax on a pair of O'neill's new Psychotec booties and all I can say after 3 sessions is WOW! First of all, the price went way up since I last bought booties - like feels like almost double the price and that was only a few seasons ago. So yeah, you could say i was excited to feel the doubly improved quality of these booties!! And the first impression of these sneakers did not let me down. I was tingling inside, instantly, and mostly in my feet from all of the water pouring into the booties on my first session. I absolutely love that familiar feeling, and that there was almost no difference between these and my ~ 3 season old booties in terms of water repulsion. This trusting company does not try to trick you: they show you exactly how their booties will feel after a few seasons, immediately, never giving you false hope by designing a booty that will repel water and feel brand new for a while. Much respect! And that second Wow moment came a few days later when the pull tab on the heel pulled right off when i was sneaking my dogs into these johns! That's right, my 3rd session in these booties and already the pull tab is breaking away - something i totally should have thought to do when I first got these things, but fortunately didn't have to, because O'neill designed these breakaway tabs directly into the booty! I could instantly feel myself going faster with the reduced drag that was being created by the pull tab in my first few sessions, and that even more water was creeping in, instantly, which helped me get in tune with the conditions that much quicker! They really thought of everything when they made these: Most importantly that I will have to keep coming back, again and again, to buy more with their ~ weeklong life span. Clever play! Couldn't Be more stoked! Most trusted name in the industry! Hits it out of the park once again! I always feel as though I'm coming up short when it comes to lighting my money on fire, and O'neill has proven to be a company that will help me do just that. Thank you all for your incredible work and breaking the mold creating a brand new product once again!!!!"
