Thermal Swim Socks

Two things are not fun when swimming:. Cold feet and feeling like you're fighting to kick your feet.

Our Thermal Swim Socks aim to lessen both of those issues by using a thin, 2mm Yamamoto Super Stretch Neoprene with our Zirconium liner in the foot area. Thinner neoprene is less buoyant, meaning easier and more natural kicking than a thicker neoprene sock or bootie. The Thermal lining maximizes warmth to help keep your feet cozy. 

Typically worn under your wetsuit, we increased the length of the sock to reduce water entry. The textured bottom helps prevent injury to feet when walking or running on rocky surfaces. They come in handy on long transition runs too. 

Available in 2 sizes.

Wish there were larger sizes
Thermal Swim Socks L
The L size was too tight for my feet. My shoe size is 47 (US 13) and the toe area was just too tight. Retuning was seamless.

Life savers. Great quality. Barefoot feel. So happy I bought them
Thermal Swim Socks L
Wore them for 70.3 IM Indian Wells, takes minimal time to take off during transition, swim just the same and saved me from feeling cold before and during the event. Life savers have highly recommend to my friends doing an Oceanside 70.3 event too. Great quality, did not feel a difference in terms of the swim feel, pace remained same as without one, so couldn’t be happier.

Good quality, but to small for my feet
Thermal Swim Socks L
I could tell these were great quality but the large was just way to small for my wide feet, size 13.

They’re ok but not great
Thermal Swim Socks L
My husband and I both bought them for swimming in a 65 degree lake. The small size fit me ok but I found it too difficult to swim with them especially for any stroke other than free style. My husband bought the large and couldn't even get them on his legs. I use mine with sandals to kayak in the cold lake and they're helpful for that. They do, by the way, fit under swim fins.

Keep feet warm
Thermal Swim Socks S
I really like the warmth that the thermal socks provide. I wear them under a pair of short flippers that otherwise are too big and it works well!

High quality neoprene swim socks
Thermal Swim Socks L
I've been using Blue70 swim socks for at least the past 10 years. Bought a wetsuit, socks and cap for an open water swim in 2014. Today swimming is more likely in a pool and I still use the swim socks. I developed peripheral neuropathy and the swim socks just feel comfortable my feet. They provide just the right amount of cushioning and warmth to make a swim more enjoyable. The chlorine is pretty rough on neoprene, but they last long enough, until I need a new pair. A pair lasts about a year in the swimming pool. Just ordered another pair and they feel great. All in all, a high quality product at a reasonable price.

The small size was too...
Thermal Swim Socks S
The small size was too big for me (my shoe size is Women's 7.5) As with the gloves, they had a decent fit when dry, but stretched and sagged around my ankles after several minutes of swimming (even though I had them tucked inside the legs of my wetsuit). The foot part continued to fit fairly well, and they held warmth, but I couldn't keep swimming in them with the ankle sagging part.
