## Assos Ultraz Winter Socks P1

The Assos Ultraz Winter Socks P1 are made for cycling when winter allows no compromises. Thanks to **three-layer insulation** in exposed zones, they retain warmth without neglecting **breathability**. A higher-cut cuff of up to **18 cm** ensures no cold bridges form between sock, tights and overshoes. The material blend with **merino wool** provides natural odour resistance and keeps you warm even when things get damp. The low-seam **160-needle construction** fits lightly compressive against the foot and prevents slipping. The model is available in blackSeries colour and in three sizes from 0 to II.

- **Three-layer insulation** at toes and midfoot for maximum warmth in cold conditions
- **Merino wool** in the yarn blend for odour resistance and warmth even when wet
- **160-needle construction** for low-seam, pleasantly compressive feel
- High cuff up to **18 cm** for seamless layer coverage
- **Breathable** fabric blend with stretch recovery properties
- Three **sizes** (0, I, II) and **blackSeries** colour for uncomplicated setup
- Developed for **extreme winter conditions** in Swiss cycling everyday life

## Technical Details and Functions

The P1 relies on a balanced mix of synthetic fibres and **wool** that combines the advantages of both worlds: efficient **moisture management**, reliable **insulation** and lasting shape stability. The **160-needle construction** reduces potential friction points and supports the foot with light compression, so nothing slips or cuts in. Targeted **triple layers** in the toe and midfoot area increase the thermal shield exactly where riding wind and spray water have the strongest effect. The cuff of up to **18 cm** high minimises cold bridges between socks, tights and overshoes. Thanks to the **merino wool**, the textile stays fresh longer and still provides warmth even with residual moisture, which brings noticeable comfort on long winter rides. Overall, this creates a functional winter sock that combines warmth, breathability and support without adding bulk.

## Applications and Benefits

These winter socks are the right choice for training and commuting routes in Switzerland when the thermometer hovers around freezing or drops below. In combination with winter **booties**, they enhance cold protection while **breathability** wicks moisture away from the foot. This prevents the typical cold feeling that can arise from sweat buildup and keeps performance stable over long distances. The **merino properties** help minimise odours, which is practical for intensive blocks or multiple rides per week. The high cuff connects cleanly with **winter tights** so no gaps form when you're riding in the lowlands as well as higher altitude regions. This creates versatile applications from daily commuting to long base rides at the weekend.

Optional: The P1 fits into the Assos winter line, which is known in specialist media for well-thought-out cold layering concepts, including targeted reinforcements at critical zones. The combination of **wool** and synthetic fibres follows proven recommendations for winter cycling socks, where warmth and **moisture transport** are equally important. Specialist articles also highlight that a higher cuff and low-seam constructions can improve wearing comfort in the shoe without adding unnecessary bulk. Those who sensibly complement their winter equipment benefit from a balanced setup of socks, tights and booties for long, cold days on the bike.
