blueseventy Thermal Swim Socks - for Triathlon Training and Cold Open Water Swimming

I bought a pair to swim in unheated pool during winter. My feet get cold pretty quickly within the first few minutes, and went numb after swimming 45minutes. I have to wear a short 3 mm neoprene sock inside this Blueseventy sock to keep warm enough for a 45 minute swim. The sock stays on well. I wear the socks inside my wetsuit. The bottom starts to peel a little after swimming for 1 month everyday. I don’t walk on land with the socks, only walk in and out of the pool and gently kick off the wall during lap swimming. To be fair, I should mention that I swim 200 laps every swim/day. So the socks start to peel at the bottom after about 6000 turns/laps (again, I don’t kick or push hard). In comparison, they are much more durable than the other cheap neoprene socks on Amazon that got dime sized holes within 2 weeks of same use. My main complaint is that these socks do not keep my feet warm in cold water. I have just bought the thicker Zone3 thermal socks, hope they perform better.

I swim in cold water - river and ocean. These socks are very comfortable, lightweight and keep my feet pretty warm. Caveat, I do have Raynauds Syndrome so my feet may get colder than most. I also scull daily to a swim spot several mile up river and these are light enough to fit well in my foot stretchers, keeping my feet warm throughout.I absolutely recommend them.

Excellent product. I have a tendency to be cold in 60 - degree water and these really made the difference for me. Usually having to put Vaseline on my face and feet during the cold open water swims to tolerate such a cold environment was a bummer. Now these bad boys saved my freezing feet. If you are thinking about getting these, do it. Well worth the price. After doing research on the best bang for my buck, these were highly recommended by well known swim magazines, consumer reports, and highly recommended by swim mates.

These may work fine for a triathlete training in water 60 degrees Fahrenheit or above, but for extreme cold they don't keep my feet warm. I'm now down to swimming in 56.4 degree F water and my feet are cold in the water and very cold when I get out.

I bought these 3 mm neoprene socks for cross country skiing and also for running in cold weather or rain. I have used them for both sports this fall and they are excellent - no blisters or other problems, and the 3 mm is just the right thickness so I fit in my running shoes and xc ski boots.

Thermal swim socks arrived on time and fit perfectly. I ordered a small and wear a woman’s 8 1/2 shoe. Bought them for open water swimming but with shelter in place and closed beaches, I haven’t tried them yet.

Excellent for cold water swim. I just finished an Ironman 70.3 in very cold water and these worked fantastic. Did not fill up with water and although they did not keep my feet toasty they definitely took the edge off. Highly recommend for cold water swimming.

Excellent product and service!

These socks feel comfortable on and don't impede swimming. They are great for having a sounder footing getting into open water, protecting your feet from sharp stones too. The only reason I've not gone for five stars is that my feet still felt cold, less quickly, but still cold. Having said that, I'm pleased I got them and they certainly help to keep things comfortable for longer.

These are well padded so even with sensitive feet you can walk around in them. The sole has a rough finish which helps prevent slipping if you’re going through mud or snow to get to the water. And they are really warm! I have been using them in water temperatures between 4 and 7 degrees Celsius.I was unsure if they would fit, but size small is just right for me (European shoe size 38). When the water was particularly cold or I wanted to stay in longer, I put them on over wool socks and they were still comfortable.

I wanted the socks to give some relief to a foot wound and they certainly help with the pain on rough surfaces. I have something in my, foot yet to make it's way out. The soles help with grip on slippery rocks. They do not seem to affect my swimming and do keep my feet a little warmer in cold water.So I am pleased with the purchase.

I love these socks - great for walking on stones etc before and after swimming too. My feet still get a bit cool, but the sock have made a real difference
