O'Neill Heat 5mm Round-Toe Boots

I've surfed for 45 years, and if Josh recommends something, it's the best! So I saw his testimonial for these booties (all of my other booties had sole holes and smelled like pee). The new booties arrived quickly with candy and a friendly note. The booties fit perfect (true to size for me) and are the best booties that I've ever owned, easy to get on and off with cold fingers, nice velcro straps, and a perfectly blended sole with great grip, I'm just learning to prone foil in surf. I feel like I'm 12 years old again, and experiencing the thrills of skateboarding for the first time.

Super Duper thanks Josh and the Cleanline Crew!

It seems like the bigger the size the taller our feet are supposed to get? Booty is very warn because its 5mm, but the fit is lacking. My toes are all the way to the end, but the vertical space in the booty is not designed for a human foot. I have to tighten the arch strap (the only redeeming quality of these booties) until like half the velcro strap is flopping off the end, and then there is still basically a water balloon in my toe area and towards my heel.

Cleanline is a great shop, but as one of only a few booties in a size 14, I think O'Neill needs to check in on that size guide

I went all over Seattle looking for boots in my size for my weekend surf lesson. Everyone was sold out because it was the end of the season. I called Cleanline to confirm my size in an O'Neill boot and the person I spoke with recommended that I size down. The boots fit perfectly and they arrived in plenty of time for my lesson!! If you have questions, I recommend speaking with customer service before you place an order online. These folks know their inventory and they're eager to help!

I've been wearing O'Neil round toe booties for a very long time. Over the years, the design remained unchanged until recently. They're still comfortable and toasty warm but the new design is a little constricting on the sides of the front of your foot and the size runs a little smaller now.

Great fit, and the keep my feet warm.

No issue with Cleanline. Great service as always! These booties felt really comfortable with a good fit. I surf a SUP so spend most of the time up on my feet. Unfortunately once in the water they expanded or something? I was sliding side to side and forward. Found myself constantly trying to grip with my toes. When I take them off they are holding about a pint of water! Very disappointing since I've never had issue with any booties before. Definitely go at least a size smaller than you would normally if buying these.

Great fit, warmth, comfort, and value. My first pair lasted a long time, and as they wore out I bought another pair because they're just that good.

They fit great and keep my feet super warm! I'm very happy with this purchase. I wear a women's size 7 and size 6 in these booties fit me very well. They shipped quickly and Cleanline Surf sent some stickers and candy!

Using for windsurfing on Lake Mohave. Water about 50F, air temps 55 and higher, shoreline extremely rocky. Boots are warm enough, flexible enough, and tough enough for the task.

First and foremost, everything you have read about Cleanline is true. Amazing customer service, fast shipping, candy and personal notes. Absolutely brilliant! Boots are great. Very warm. Fit a little on the snug size (size 10.5, bought 10) but am sure after a few more not cold sessions they’ll be good.

These booties are the best I have found for fit, function, price and value. The arrived a few days after my order and I was not disappointed.

I have been wearing O'Neill round toe booties of differing mm's for years....love them! I wore a size 9 (last ordered 7mm about 5 yrs ago) and this order and one last year I tried 3mm and 5mm but they were so small, my toes were curled. I went to a size 10 and they fit just right. Also thanks to Cleanline for easy returns!

Never worn booties before, but bought these because I started surfing in NorCal. Worked great and did the trick

Plenty warm and comfortable fit!

Called cleanline to give me a recommendation for a winter boot in early Jan. They recommended me these and I could not be happier, they are perfect! Super warm, and make the walk from the parking lot to the beach so much more bearable. I’ve found them to be plenty warm in water temps around 55 degrees (though they are extremely thick and you could definitely wear them in colder). They feel really well constructed, and the straps are great for making them fit snugly.

Sizing wise, I bought an 11 and I generally run anywhere from an 11-11.5 in regular shoes. They definitely feel a little tight when I first put them on, but in the water expand to the perfect size. I would say go TTS if you’re buying these for the first time.

My son and I both wear these. Nice slim fit. Warm. Teue to size. Quality. Buy them.

Great booties fit and feel great and very warm with no filling issues, all around good booties highly recommended.

My feet are finally warm. Very happy. Great price too.

Really makes a difference surfing in the winter in SoCal, can't go surfing without them

It’s like a hot tub on my feet

Love these guys. Never had a cold water flush with these. And the full rounded toe is so much better than the split tow booties.

My 14 yr old son convinced me to purchase these and I couldn't be happier. Fit great with good feel. Warm as can be in the Pacific NW.
Thank you CleanLine Surf!

More like warm slippers with great feeling for control.

I’ve been wearing this bootie for probably ten years and in my mind it is the best most comfortable bootie on the market. I’ve always worn size 12 but the last two pair have been tight to get on and as a result I ripped out the heel. so I just bought a size 13 because they are the best booty on the market.

Keep in mind this might have just been a quality issue with my pair. Fit and responsiveness felt good, but seams let water in immediately and these weren't as warm as my booties from other brands. Plus, the rubber just above the heel ripped after ~10 sessions.

I typically like O'Neil, but I wouldn't buy these again for the spots that I surf.

I have worn Rip Curl suits for years, and I am a big advocate for the Flash Bomb lining, which IMHO makes for the warmest suits.I have always worn Rip Curl gloves and boots as well. Recently, I noticed my 5mm Rip Curl boots were ballooning with water after each surf. I just purchased a pair of 7mm Rip Curl boots for the winter, and these too fill up with water quite quickly. When I leave the water my feet are like balloons...the neoprene in the Rip Curl boots is very soft and stretches with water inside the boots, which in turn causes fitment/traction problems. Decided to listen to Josh (owner of Cleanline) and pick up a pair of these boots. Surfed them this weekend in Rhode Island. They kept my feet warm with minimal flushing whatsoever. They have great rubber traction as well. The rubber wraps around the entire foot which keeps them from flushing. Also the neoprene is a bit stiffer, which helps for boots. I never write reviews but I am so stoked on these boots. Much better than the Rip Curls. Thanks Josh and Cleanline.

If you are used to the old Heat booties, these fit quite a bit tighter. Not really a terrible thing, unless you're sitting for awhile waiting for the wave of the day. I prefer the old soft sides which let a little water in to warm up next to your foot but these are still a good boot.

I never was a fan of booties as even split toe versions would be like two giant water balloons on your feet. Then you can’t feel the board. These boots are a totly different story!

While I was scheduled to be surfing in Wales, UK right now a new job my Wife got has us delaying the trip, so I have not ocean surfed them. So what am I doing reviewing? Here in the mountains it is spring run off time on water that was snow or ice a few days ago :-)

I’ve suffered some nerve damage from having a 6,000 pound pickup truck tire drive over my scapula, ribs and spine. I should be dead so walking away with just nerve damage (ok shattered scapula needed 4 plates, 27 screws and 40 staples, 9 broken ribs and both lungs punctured) so the excruciating pain I feel when touching water below 75 degrees is the this boots test! Oh yeah, I’m size 14 with Vikings for ancestors lol.

We get truck inner tubes and shoot the creeks swollen with the melt. I put my new O’neils on and an ancient short john and walked into the creek (between 47 and 52 F) and wonder if I got the wrong boots. Are these dry boots? The two straps do a great job of keeping the water from flushing which my vintage pair could not. I never felt the cold water enter but 20 - 30 minutes later I noticed that jiggle of water in my boots yet it didn’t feel like heavy water balloons! You don’t know what a big deal this is! I’d rather drop a sledgehammer on my toes than spend 30 minutes in the water with out these boots!

I can’t comment on durability, but for heat and comfort how can you do better?

I haven't had a chance to take these out in the mid-Atlantic yet, but right out of the box, it's a great fit! I wear a women's size 8.5 so I ordered an 8 based on the size chart, which I would say is accurate. I think O'Neill tends to run thin/narrow, which actually works out great for my feet. I appreciate the thoughtful touches from Cleanline Surf- they threw in some starbursts, a cute surfer decal, and a post card!

My surf boot of choice for the last ten years has been the O'Neill round toe Heat. It fits like a glove and is more like a slipper than a heavy bulky boot. It has toe and heel caps for durability and fluid taped seams to keep water out and give more strength and longevity to the seam. It has a firewall lining which makes it warmer and very easy to get on and off. I am so confident in this boot that I put 150 pairs into our rental fleet this year alone. I've worn a lot of boots but this is my personal favorite!
