Technical information

Comfort and thickness

Unlike the RUN900 FINE sock, this RUN900 THICK sock contains thicker zones woven with fine loop pile fabric for greater comfort and/or cushioning.

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.


The black and white models are woven with dope-dyed yarn.
Dying textiles requires a lot of water but produces a lot of waste water from dye baths. In order to reduce this impact on the environment, we have chosen to use dope-dying, with the colour pigments integrated as the yarn is manufactured.
