ON’s Merino Ultra Socks are designed for runners who need extra support, protection, and comfort on trails and road runs. Their ergonomic design supports the foot from the toes to the heel and ensures a secure, natural running feel — even when the terrain gets challenging.

Open mesh channels promote air circulation and keep your feet pleasantly cool, while temperature-regulating merino wool ensures a balanced wearing climate. Targeted cushioning made of soft terry fabric on the arch and heel offers additional protection and comfort with every step.

The anti-slip technology underfoot prevents the sock from sliding inside your shoe and gives you a secure grip, even when you pick up the pace. At the same time, low-friction yarn ensures a comfortable feel without distraction. Reflective yarn on the cuff rounds out the functional design — for high-performance socks that have been tested by athletes and reliably accompany you through trail runs, road runs, and intense training sessions.
