Running socks

Ian L.
Great winter socks, maybe summer too but can't test that yet.

Perfect fit, warm, comfortable and work really well on my long runs (15k+) - would recommend.

Great to hear that you are loving the Merino Mid Socks, These can be worn in Summer too and will keep your feet at a good temperature without feeling too warm.

Thank you for your purchase with Runderwear.

Simon Baker
Second pair for the winter

These are now essential to my winter runs. I’ve been out in near freezing conditions this year, mostly running in the evenings.

My feet are absolutely comfortable throughout my runs with no hint of cold, and crucially no overheating.

These are an absolute necessity for me. I took the plunge a while with a long sleeve base layer, and added Runderwear merino boxers and these merino socks to my running wardrobe as the weather got cooler.

It’s a balmy 5°C outside right now, and I’m going for a 12k run in the knowledge that my Runderwear gear has got me covered.

Excellent socks.

Thank you for your review, Great to hear that you are loving your Merino Mid Socks and they are now your essential winter go to. We love to hear this.

We hope you have many happy miles in your Merino Socks!
