Product Description
Features
Merino-rich construction and targeted heel and toe padding support comfort in changing conditions.
Reinforced zones add durability for regular use; midfoot rib compression helps keep the sock in place.
Ventilation mesh encourages airflow; a flat toe seam helps reduce rubbing.
Recycled polyamide supports shape retention and fit.
Details & fit
Crew height: approximately 4 inches above the ankle, providing coverage without sacrificing ventilation.
Size up if you have wider feet or are near the top of your size range.
Machine wash on delicate cycle (max 30˚C), using an eco-friendly delicate washing liquid. Personally, we recommend Nikwax Woolwash and a max spin of 400rpm.
These lightweight merino crew socks excel for running, hiking, and multi-sport activities. Customers praised exceptional comfort, durability, and performance across various conditions. "The best socks I have ever purchased," noted one reviewer. They provide warmth when wet, prevent blisters, and stay up well. Minor concerns include color options and heel reinforcement placement.

Tried these socks out on a recent trip to the lakes. I was very pleased with the comfort level tackling wet conditions under foot. I have recommended Moggans socks to my fellow walking mates.

This is the 4th pair of Moggans socks that I have bought in the last 4 years . Without any doubt, they are the best socks I have ever purchased! They are well made, cushioned, very comfortable and last a long time !

Another great pair of merino socks , very comfortable to wear . When I bought my first pair of Moggans I was very sceptical as I wear through my socks very quickly however they do last !!

Love the socks as they stay up in wellies. Could just do with the heel reinforcement being a little higher up the back.

A genuinely amazing trail running sock. By some alchemy, Moggans have managed to create a padded sock that is both warm AND cool when required, while also preventing blisters.
Oh, and they're super comfortable.
I'll be wearing mine for the 2026 UTMB Arc of Attrition....and if I can find the cash will be buying at least one more pair.
Highly recommended.

So far so good; don't notice them on my feet - which is what you want with a pair of running socks out on the trails. The lightweight has a good thickness for winter running.

Very comfortable lightweight socks. I use them for walks and motorcycling, quite warm considering the light weight.
I also have some Moggans heavyweight socks for winter use on the motorcycle but they are too thick for my walking boots which is why I bought the lighter weight socks.Prompt delivery from Moggans. Brilliant socks thank you.

i am impressed with the service, I bought the wrong socks and wanted to swop them. i was emailed back the very next day, this was no problem. in the end i decided to gift them as Christmas presents and buy the ones I wanted
My Moggans socks performed very well on last week’s ultra in the Balkans. Not a sign of a blister or hot spot. All around comfort. Thanks! A great product.
