Important note:

  • Recharge the S-Pack battery after each use. This extends the service life of the batteries and ensures that the device is always ready for use.
  • The battery consists of lithium ion cells and can be charged in any state. For this reason, the battery does not need to be fully discharged before charging.

  • Do not allow the highest heat level to be switched on for more than a few minutes at a time. This could produce too much heat during operation, which may cause burns.
  • Always set S-Pack battery to low or moderate heat levels to maintain comfortable foot warming (heating should be almost undetectable).
  • The optimum heat output is only reached when the socks, boots or soles are dry.
  • Never used the heatable sock and the heatable insole together; this can result in too much heat - risk of burning!

In 1975, Sidas was established by three ski instructors looking for ways to make skiers' feet more comfortable. The brand founders decided to make insoles moulded to each individual foot shape to provide more sensation and reduce discomfort inside ski boots. Not having specialised tools to hand, they moulded their first insoles with an oven dish and a cushion! The venture was a success, and so began the company's long history! Sidas then began to grow rapidly, providing comfort solutions not only for skiing but also other sports such as running, outdoor sports and cycling, and for everyday footwear too. Ten years later, in 1985, Sidas turned its attention to a new market: medical. Using Sidas technology, the company founded the Podiatech brand, offering approved foot professionals solutions for their patients' feet. For 40 years, Sidas' growth has been assured by its commitment in different areas: Innovation, Passion and performance, Commitment. Sidas provides solutions for every type of foot and every sport, every day.

Since its creation, Sidas has drawn its force from four essential values:

Innovation, Passion, Performance and Commitment.

Sidas is the ideal partner for all those wanting to offer their customers the best technology, for all foot types, for all sports, all the time.

Footprints are like fingerprints: yours are different to everyone else's. Every individual has their own unique way of walking, and SIDAS has taken the right step by creating custom-fit products that are equally unique.

Great product, terrible customer service
February 7, 2021
Ordered 4 of these for our family for skiing this winter. 3 out of 4 of them worked great - the elastic band that helps hold the battery in place could use some reinforcement, but that's not a big deal. The 4th pair was defective - one of the socks didn't hold a charge. While customer service initially was responsive in sending a return label and taking both socks and the battery back, the follow-up has been completely miserable. They were supposed to send me new socks. But it's now been nearly a month, I still have nothing, and no solution for my feet while the company has my $300. In my view, new socks should have been sent right away with expedited shipping, no questions asked. Absolutely awful customer service for such expensive products.
  • The socks that did work are great. LV socks are super thin - 2 of us have those MV socks are still on the thin side. All are comfortable inside the boot. The footbed warms efficiently and the battery life is great - we didn't have problems with them turned on medium to higher temperature settings all day, and they still had plenty of life. Your feet won't necessarily feel hot in the socks; just comfortable and not cold.
  • Elastic band that helps hold up the battery needs better sewing reinforcement - it shreds a little after a couple of wears.
