“I live in Maine and have been doing some lake swimming in 52-56 degrees. The socks are comfortable but I still find my feet get really cold/numb after a 2.5-3km swim (40 - 60 min), would be great if they could be made from a thicker neoprene.”
“These socks get high marks for warmth in water as cold (so far) as 50°F. They are a bit fragile as mine separated from the heel piece after 6-months, probably due to walking on cobble. I've replaced them with another pair that I over sleeve with low-rise surf booties. Seems to be a good combination.”
“The blue seventy socks fit nice and snug but they are not warm enough for winter swimming at 45F so I wear them under neoprene booties made by another company. As another reviewer notes, I look forward to wearing the blue seventy when the water warms a little.”
“A great swim bootie that works in moderately cold water. It's really lightweight which makes kicking feel really natural. However, it is a bit too thin for water below 40F/5C. I opted for a 3mm C-skin bootie for these colder temperatures, but as the water warms, I will switch back to these thermal socks as the 3mm C-skin booties are a bit heavy/draggy.”
“I bought these to wear with my BS thermal reaction wetsuit (which I LOVE) I swim in an estuary where winter water temperatures range from mid to high 40s. I wear flippers and these keep my feet from turning to wood stumps and fit comfortably in my flippers. I did wear holes in my first pair from walking across the parking lot but have purchased some crocs to wear to protect my new pair. Just add crocs to your gear list and you are good to go!”
“I wore them when the SF Bay water temperature dropped to 54F and below. They are not waterproof like your rainboots but they make huge difference on protecting your feet (therefore your body) from the cold water.”
