Keen Springwater Socks



Ultra-comfy left and right specific cycling socks that (almost) never go smelly

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

I'm a big fan of Keen shoes, and I love stuff made from Merino. I was expecting quite a lot from these Keen Springwater socks. They don't disappoint.

They are made from a clever mix of 50% merino wool and 50% synthetic stuff. In my experience, it's pretty important to get this mix right. Too much synthetic stuff and the smell-stopping merino can't work its magic. Too much wool and holes start appearing too quickly. So far, the evidence suggests Keen have got it right.

These are right and left specific, which makes them fit like the proverbial. The size I tested is marked as a (European) 37-42. I take a 43 or 44 in cycling shoes. Best to err on the small side, as with most socks.

The socks are bike specific in that they have a different material under the forefoot to provide a bit of cushioning. There's a bit more material around the ankle too to relieve pressure from the lip and cup of the shoe. The top is made from a mesh to give a bit of ventilation and the toe is seamless to stop them bunching up. That is what it says on the tin and I can confirm that it all works rather well.

The wool comes from Australia and the socks are made in the USA. That, combined with the clever features and the left and right specific cut, will explain the price then.

I love wearing these all day long, before during and after rides. And again the next day and the day after. Yes, they are a bit pricey, but you get what you pay for.

Rate the product for quality of construction:

They seem very well made and haven't fallen apart yet.

Rate the product for performance:

Great to wear on and off the bike and you have to wear them a REALLY long time to get them smelly. Gotta love merino.

Rate the product for durability:

So far, so good. In my experience merino socks last less long than synthetic ones, but I'm hoping the clever mix of nylon and merino will mean these last longer. Certainly no signs of wear after a month's intensive use.

Rate the product for comfort, if applicable:

Very comfy. Did I mention I love merino? The right materials have been used in the right places.

Rate the product for value:

They are a bit expensive for a pair of socks, they're even more expensive than DeFeet merino socks (though not by much), but you do get quite a lot of different materials put together in a clever way, and they are right and left specific. I reckon it's a price worth paying.
