Always thought socks were socks, but these are next level and amazing to wear. They grip your foot perfectly with no hot spots. They worked a dream during my ultra training and even better during the Lap. Definitely getting more.

These guys do the best socks. They looks cool, have a really high quality feel to them, and most importantly, they perform really well. Do your feet a favour and invest in several pairs. I know I will be!!!

So far so good. After roughly 50km of running, no issues or discomfort. These seem to be great quality, they are super comfortable and look great.

Very happy with my purchase. After seeing plenty of advertisements on social medias I decided to give it a go. Ordered 2 pairs and so far not regretting it. Or maybe of only ordering 2 pairs. The short socks are super comfortable and fit under my calf sleeves which is why I was looking for. Long pair also very nice to wear and looks great. Looking forward to many more miles together !

I like the socks, they feel light but supportive. However even the largest size is quite tight for someone with relatively big ankles/calves.

Very good running socks. Having spent too much money over the years on the bigger brands, none have fit better and looked after my feet more. 👍
