Product Description
Features
Featherweight Merino is 32% finer and lighter than our original crew socks, helping keep feet dry and cool.
Reinforced heel and toe add durability; midfoot rib support holds the sock in place.
Ventilation mesh maximises airflow; a flat toe seam supports comfortable all-day movement.
Recycled polyamide provides a performance-focused fit.
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 ultralight Merino crew socks receive excellent reviews for running and cycling. Customers said they're "nice and lightweight" with "good quality" construction. One shopper noted they feel "even better than barefoot!" The socks are praised for comfort and fit, though sizing advice suggests going down if between sizes.

Great socks. Nice and lightweight for my new grounding shoes. Good quality. I accidentally ordered small when should have ordered medium and the company swiftly swapped them for me.

Very comfortable, well made socks. I am a size UK8 and find the size 5-7.5 fit me perfectly so I would suggest sizing down if you are in between sizes.

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.
