FAQ
Frequently asked questions
Is the battery included?
No. A compatible S-Pack battery is required separately.
Is it suitable for tight ski boots?
The heating line is thin, but very tight race or low-volume boots should still be tested with the sock.
Can heated socks solve every cold-foot problem?
No. Excessive pressure or poor boot fit can reduce circulation and should be addressed first.
Are heated socks suitable for tight ski boots?
The heating line is thin, but sock thickness should still be checked in very tight race or low-volume boots.
How should I wash heated socks?
Remove the battery and follow the manufacturer's care instructions; this model is intended for gentle low-temperature washing.
Which heat level should I use?
Start low and increase only when needed. This saves battery and avoids unnecessary heat.
Do heated socks solve every cold-foot problem?
No. If the boot is too tight and restricts circulation, the fit should be corrected first.
