O'Neill Heat 7mm Round-Toe Boots

Magic. These are the best boots I've ever experienced. My feet are always the coldest part of me when I'm out on the water. Literally feels like I'm standing in bath water even when standing in the cold winter water for an extended period of time. Highly recommend to anyone that wants to be warm and cozy!

These boots have served me well for 15 plus years. North East winters they thrive. The double strap is key. Great traction and durability. Keep them doggies toasty in the low 40’s…. Love the whole crew at cleanlines… You guys rule … Thanks…

Nice product and good features. A bit narrow for my chunky feet. I like to have my toes splay a bit.

I wanted to try some 7mm booties after my feet were getting a little cold. Quite a bit warmer than 5 mils so I look forward to wearing them through winter. The Heat fit is legendary and these don't disappoint. I'm a true size 10 and am glad that I ordered an 11.

Got these for New England fall and winter surfing. Been using them in the fall so far and kept my feet plenty toasty. Able to go further in the season with my 3/2 wetsuit because of these boots.

So far they're toasty warm and fit well. I've only had them a month, so can't attest to their durability.

My wife has been wearing these booties for 35 years been through dozen pair warm like bedroom slippers in cold water of the great lakes

I actually havnt used the boots yet bc i got em at end of winter here in NJ. 5mm got me through (barely) looking to try em out next winterm

Comfortable and warm for frigid New England surf sessions! Excellent quality.

Size 14 fits 14.5 in comfort.
Fresh-water paddle-tested to 33°F. Surf tested to 40°F. Very Low leakage. Always toasty.
Easy on/off, and sure footed for 7mm thickness.
Warmest booties I’ve owned in 45 years of surfing.

The answer to world peace especially with gloves and well.

Boots are very warm, I'm on my 3rd pair. Early spring water 33° in Michigan. And on the other end late fall into the winter, ( if you can find open water ). Bottom line, if your going into a cold environment ( 33° water temps ) these booties work great

I stand up paddle as long as I can into the winter season in Park City, Utah. If the water temperature stays around 34-36 in the winter then the lake does not freeze over, however, that is fairly cold water sloshing around my feet. i have only used the booties once this winter and the water temperature was around 45 degrees. I paired it with a thin bootie liner sock and my feet could not be happier unless they were submerged in tropical water.

They take some getting used to since they are so thick but I was pleasantly surprised at how comfortable they were. They did not make my feet feel more tired like thicker wetsuit material tends to do. The booties sealed up nicely and exceeded my expectations.

The rear loop looks like it is installed really well but I suspect if that loop ever failed it would be nearly impossible to get that thick of a bootie past your ankle.

The size fit as I would have expected. I typically wear a size 11.5 men's and I purchased a size 12. With the thin liner sock I have just the right amount of room. It looks like the lake will freeze this year so the back country ski gear is is loaded in the car.

Thanks to the Cleanline crew, they provided a great product and awesome service!

I am skinny. 5'11" 145lb. I hate cold. But I love NE surf and do it all winter. It's not recommended because hot water is bad for tape, but I will soak my booties and gloves to saturate with warm water (body temp) then put them on and hit the water. I spent three hours in the water in February one day in a 6/5/4 flashbomb suit, flashbomb 7/5 mitts and these very booties. 3 hours is a long time when the water temp is 37 and air temp is 7-degrees on my car thermometer, nevermind wind chill.

I have been wearing these boots for two seasons and love them (when it is super cold I wear 1mm watersox with them). I'm now a diehard cold weather guy and nobody knows that when I get home I pour the boots and gloves out and the water is 98.6! I'm not kidding.

So they break down after three or four years... I'm ok with that. Given how warm. Yes. Water gets in slowly (when you start dry). But it is very slow and totally manageable. In fact, the water is what keeps you warm. Otherwise, without water for your body to heat up, the 38 degree force of nature OUTSIDE the bootie is going to win the battle. It always does.

These booties are best I have ever had. I wear size 14 and they are just a bit big which is really good. The 7 mm eliminates the cold at 55 degrees. The cinch is well designed and did not allow any water into the booties.

Test fitted in bathtub. They filled with water with in 30 seconds (made in China). Water level was to ankle bone. The inside Glue and tape were missing in spots. Called Cleanline and 5 minutes later the crew had a pair of Quicksilver Highline 7mm. They are leak free.
