A great ally for winter sports.
It's warm without being too stuffy.

Made with newly developed moisture-absorbing and heat-generating yarn, it keeps you at a comfortable temperature even when playing sports without getting too warm. The part above the ankle is made with long brushed pile, and the part below the ankle is made with pile knitting to make it easier to wear with sports shoes.

The development process of "Heat Love Socks Sports"

These popular winter socks, with the catchphrase "Warm from the moment you put them on," have been repeatedly renewed since their release in 2009. They have been well-received as sports socks that keep your feet warm even in winter.

However, we received feedback from customers that the socks were too thick for wearing with shoes, so we designed and improved two new products that can be used for both relaxation and sports. We propose "Heat Love Socks Relax" as socks for relaxation and "Heat Love Socks Sports" as socks for sports.

In addition to being warm, the Heat Love Socks Relax are four times thicker than regular socks and don't feel too tight, while the Heat Love Socks Sport are thick enough to not feel too tight even when wearing shoes, helping to reduce fatigue.

Optimal compression

It has a moderate compression that is not too tight, making it comfortable to wear even for long periods of time.
The gentle pressure helps prevent swelling in the feet.
It is recommended not only for sports, but also for people who tend to get swelling due to standing work or sitting for long periods of time.

arch support

It tightens the arch of the foot (with strong compression on the inside) and prevents muscle relaxation, which can cause fatigue. It also prevents the arch from collapsing, making it recommended for people who work standing up or who move around a lot.

Air ventilation

Zerofit's unique grooved, uneven structure (air ventilation) creates airflow inside the shoe, reducing stuffiness and keeping your feet fresh.
It also has a massage effect, helping to reduce fatigue.
