Never cold feet on the bike again: the heated sock for in your cycling shoes

If you regularly ride a road bike, you undoubtedly recognize it: cold feet during chilly rides. Even with thick overshoes and merino socks, it remains a struggle as soon as the temperature drops. But thick socks don’t fit into your tight-fitting cycling shoes, and heat loss through the toes is always lurking.

Fortunately, we have the solution for that: the HeatPerformance® ULTRA THIN socks – our thinnest heated socks, specially designed for a perfect fit in close-fitting cycling shoes.

Thin, comfortable and heated

Cycling shoes are stiff, tight and designed for performance, not for comfort in low temperatures. This makes it virtually impossible to wear thick winter socks or standard heated socks.
The ULTRA THIN breaks through this problem: This sock is as thin as a normal sock, but it is equipped with powerful heat conductors placed above and below the toes – exactly where you first experience cold on the bike.

Up to 6 hours of heat on the bike

Just press a button to activate the built-in heater, which provides up to 6 hours of heat – depending on the setting and outside temperature.
The socks run on a 7.4V – 2600 mAh lithium battery that can be tucked away in your sock or, even more convenient while cycling, with an extension cable in the back pocket of your cycling shirt or jacket. This way you maintain maximum freedom of movement and a tight fit in your shoes.

Cycling with feeling – no clumsiness

What makes this sock truly special is that it remains wonderfully light and supple despite its technology. You feel no wires or hard elements, and your pedal feel remains intact – essential for those who train seriously or go on long trips. So no thick thermal socks, no thick overshoes that barely fit over your shoes – just your own cycling shoes, your favorite click pedals AND warm feet.

Also suitable for other sports

Although this sock was really designed with cyclists in mind, it is also ideal for skaters, inline skaters and other sports where you deal with thin, tight shoes. Or just for everyday use when you’re looking for just a little extra warmth in your sneakers in the fall or spring.
