Product Description
Features
Targeted lightweight cushioning and reinforced heels and toes add protection without bulk.
Midfoot compression supports the arch; a deep welt helps prevent slipping beneath the heel.
Ventilation mesh keeps air moving; mulesing-free Merino provides temperature regulation, moisture management and natural odour resistance.
Invisible toe seam helps reduce chafing and irritation.
Thin Merino-blend construction dries quickly after washing.
Details & fit
Height: no-show, designed to disappear inside low-cut running shoes.
Cushioning: ultralight with targeted zones.
Choose ankle height for more coverage, or crew height for trail-debris protection.
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.
Customers praised these ultralight running socks as "some of the most comfortable" they've worn. Reviews highlight excellent temperature regulation, blister prevention during marathons and half-marathons, and no rubbing. The merino wool material stays fresh between washes. One customer notes sizing runs small and recommends buying larger.

I had been looking for decent summer socks for ages. So pleased I found these. They're brilliant. Super comfy, keep feet cool on hot runs and can rewear without stench compared with other socks I have previously tried. Very happy with these. A*

All Mogans socks are. excellent, and merino wool is - in my opinion - the best breathable material there is. My only proviso is that I always buy a size too big as the socks seem to come up small, but that is a matter of preference. I rarely find superb socks in white, and after finding Mogans, I only buy theirs. Recommended.

Best running socks I’ve ever had. Incredibly comfortable. I run 40 miles a week in them. Just the right thickness. Warm on these really mornings. Bought 4 pairs. Getting a few wears out of them before having to wash them. Highly recommend.

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.
