The Comodo RUN9 is a performance running sock built around hydrophobic Polycolon fiber to keep feet feeling dry on the move. Blending 40% Polycolon, 35% polyamide microfiber, 15% polyamide and 5% polypropylene, and weighing as little as 30 g (1.06 oz) per sock, it is engineered for runners who want moisture pushed away from the skin and reinforced protection where their feet take the most punishment.
Our gear specialists selected the RUN9 as a focused piece of outdoor clothing for active runners rather than a general everyday sock. Its mid-season rating and technical fiber mix make it a strong match for training runs, tempo efforts and race days where a dry, stable, blister-resistant fit matters more than casual comfort.
Who are the RUN9 running socks for?
The RUN9 is made for runners - road, track and light trail - who care about staying dry and blister-free over distance. It suits regular training runners, tempo and interval sessions, and race days where a secure, non-slip fit pays off. Because it leans technical and mid-season, it is a better match for active use than for lounging or cold-weather layering, and a smart choice for anyone who has struggled with soggy or sliding socks.
What is the Polycolon core in the RUN9 socks?
The 40% Polycolon core is the headline: a hydrophobic fiber that does not soak up sweat, instead pushing it outward so it can evaporate. The 35% polyamide microfiber and 15% polyamide add strength and a smooth hand, while 5% polypropylene reinforces the moisture-moving performance. Structurally, the double welt, elastic midfoot band and flat seams work together to hold the sock steady and reduce the friction that leads to blisters.
How do the RUN9 socks compare to cotton socks?
Against a soft cotton training sock, the RUN9 trades plush comfort for genuine moisture management - cotton holds water, Polycolon sheds it. That makes the RUN9 the better pick for sweaty, higher-effort runs and warmer conditions, where a dry foot means fewer blisters. Its reinforced impact zones and locked-in fit also set it apart from thin fashion socks that shift and thin out quickly under running loads.

Key features
- Hydrophobic Polycolon fiber moves sweat outward and dries quickly, supporting a dry feel that helps prevent that heavy, soggy-sock sensation on longer runs.
- Reinforced heel and toe zones add padding and protection where blisters and impact hit hardest, extending sock life at the wear points.
- Double welt cuff grips the leg to stop the sock slipping or twisting inside the shoe during repeated foot strikes.
- Elastic midfoot band wraps the arch for a stable, secure fit that stays locked in through fast changes of pace.
- Flat seam construction reduces friction at the toe and other contact points, cutting a common cause of hot spots and rubbing.
- Very light at around 30 g (1.06 oz) per sock, so it barely registers on the foot and packs down small for travel.
- Technical four-fiber blend balances moisture control, stretch and durability in one running-focused sock.

Questions & answers
RUN9 FAQ
Do the Comodo RUN9 socks keep feet dry?
Yes, they are designed to keep feet feeling dry. The hydrophobic Polycolon fiber does not absorb sweat and instead moves moisture outward where it can evaporate, which helps you avoid the heavy, damp feeling that leads to blisters on longer runs.
How do these socks prevent blisters?
They fight blisters in three ways: reinforced heel and toe zones add protection at high-impact spots, flat seams reduce friction where rubbing usually starts, and the double welt plus elastic midfoot band stop the sock slipping so it does not chafe.
How much does a RUN9 sock weigh?
Each sock weighs as little as 30 g (1.06 oz), making it a very light, low-bulk running sock. That minimal weight helps the sock feel like a second skin inside a running shoe and keeps it easy to pack for travel or racing.
What season are these socks best for?
They carry a mid-season rating, making them well suited to spring, autumn and mild summer running. The dry-feel fiber also helps in warmer efforts, though they are built for active use rather than deep-winter insulation.
Do they stay in place while running?
Yes. A double welt cuff grips the leg and an elastic band wraps the midfoot, so the sock resists slipping and twisting even during fast pace changes and repeated foot strikes over a long run.
