Product Customer Reviews

Sock that holds very well without tightening at the top.
Good value for money
I HAVE ALREADY PURCHASED THIS PRODUCT NO WORRY
Very good socks. I usually buy kiprun they are solid, quite thick and comfortable compared to the "gentle slope" which is a little less effective.
good product
Good size
The truth is that they fit very well, they are comfortable and they fit well on the foot. No chafing. Maybe a little thin for winter, but once you get into the race you don't notice it.
Good running shoes are great, but you also need to think about the right socks! I am very satisfied with this pair for 10/20km Trail running outings
It feels very silky and covers well.
Very satisfied, maybe a less strong color would have been better
Comfortable
Decent product but poor value for money, basic product, you can find better at this price.
Ideal for every day
Very good product: comfort, solid, original color,...
Good product

Additional Product Information
Composition
Socks: 96.0% Polyamide, 4.0% Elastane
Height
stops just below the calf
Yarn used in the heel and toes.
We have woven these socks at the heel, toes, and necessary areas with a specific yarn to reduce the risk of developing blisters.
Special seam around the tip.
There is a special construction at the tip that makes the sock conform to the shape of the toe area perfectly.The seam at the toe enclosure is located under the toes in the hollow area to prevent chafing on the top of the foot.
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.
