Product description
When every millimetre inside the boot counts. Sidas Ultrafit Race is designed for alpine skiing and for those who prioritise precision and close boot contact. Its ultra-low volume makes it especially suitable for tight-fitting race boots, where extra material can easily affect the fit.
A silicone yarn grip strip under the foot improves contact with the boot's sole and helps keep the foot in place. This provides more stable contact and supports direct power transfer as you load the skis.
Compression of 20-30 mmHg gives a firm, close fit around the foot and calf. The sock follows the body like a second skin and stays smooth even during active movement inside the boots.
The socks are finely knitted with 200 needles and use an In&Out construction without cut yarn ends inside, creating an even feel against the skin. The material blend includes organic merino wool and silk; the merino wool provides warmth and helps wick moisture away.
Material: 35% organic merino wool, 22% polyamide, 20% recycled polyamide, 12% silk, 9% elastane and 2% silicone.
