Product Customer Reviews

Nice to wear
I wanted thick socks as stated in the description. Unfortunately these aren't really much thicker than ordinary socks.
Fantastic socks. Going back to get more
Thanks so much for letting us know how much you enjoyed these socks, Craig, and we couldn't agree more! We look forward to helping outfit you for many future outdoor adventures!
The fluorescent yellow/green is a great choice and the socks are labelled for left and right feet. A little thin, but they do the job.
Daughter had a mini triathlon to do but had no socks. She said these were pretty good
Kalenji socks are the best- doesn't break the bank and prevents blisters. What more could you ask for?
Good socks and wash well.
Well designed socks that stay snug in all activities. Extra thick on the toes, heel and weight bearing areas that get the most friction. Perfect for walkers and runners.
A great fit and really comfortable
Having used Thor Lo Experias for years, I need a change and having had these a few weeks, so far so good.. Keen to get a second pair..
Needed to replace my running socks which I brought 3 years ago with same design.they are still very comfortable and hopefully last as long as my old pink socks. Shame there is not much of a choice of colours in store, as online.
Live them. No blisters!
yep - Great socks good price
Comfortable.
Good for running and trekking

Additional Product Information
Composition
Socks
- 4% Spandex
- 96% Polyamide
Comfort and thickness
Unlike the RUN900 FINE sock, this RUN900 THICK sock contains thicker zones woven with fine loop pile fabric for greater comfort and/or cushioning.
Wash before a race
I recommend that you test out all these new products if you want to wear them in a race. That way, you can be sure of avoiding any nasty surprises on race day. As you wash them, our socks will lose the silky feeling of new yarns. Your foot will slip less in the shoe.
Extra sustainable development information
The black and white models are woven with dope-dyed thread. Dying textiles requires a lot of water but produces a lot of waste water from dye baths. In order to reduce this impact on the environment, we have chosen to use dope-dying, with the color pigments integrated as the thread is manufactured.
