The KEIS S302 Heated Socks are performance-ready thermal oversocks built to fit over your regular socks and inside your boots. Equipped with Micro Alloy‑Fibre (Micro Carbon Fibre) heating technology, they deliver even, sun-like warmth across your feet. Dual-powered via your bike's 12 V system or a KEIS portable battery, with included Y-lead for neat cable routing. Durable and water-resistant—perfect for commuting, touring, or cold-weather riding.
Got this for heated trousers. Ppl say it can be hard to locate the ordinary controller. Installed app. When bt controller is power you just cycle through the power levels. V easy. The controller just needs power. It does not have to be on. It would be good if the app was digitally signed by Keis and not the developer. I have not used the controller yet on the bike so cannot comment on reliability.
After years of layering up in cold weather and giving the lads stick for wearing heated gear I’ve joined them. My only regret is not having done so a lot earlier in life.
Arthritis makes me prone to pain on cold rides, this jacked is warm even when unplugged, but comes with three heat settings. I also bought the G701 heated gloves which are superb and again three heat settings
Jacket comes with wiring for 12v battery hook up and a FOC controller attached to the jacket.
Great value at £200 jackets £190 gloves
Note- no more layers just a Zerofit long sleeve theremal and the Keis as a mid layer and riding jacket over
The KEIS S302 Heated Socks deliver consistent foot warmth for motorcyclists, winter sports enthusiasts, and outdoor adventurers. Using Micro Carbon Fibre heating technology, they provide even Far Infrared heat across the toes and forefoot—critical areas for circulation and comfort in cold conditions. Made from a breathable, moisture-wicking blend, the S302s keep feet dry while preventing heat loss. Ideal for skiing, hiking, or commuting, these socks help maintain comfort in freezing temperatures. Includes: S302 Heated Socks (pair), 12V Vehicle Supply Lead, instructions.
Even Foot Warming with Micro Alloy‑Fibre
Advanced Micro Carbon Fibre panels provide consistent heat across the sole and toes, preventing cold spots and delivering reliable warmth without extra bulk.
Run from your bike’s 12 V outlet or a portable KEIS battery for off-bike use. The included Y‑lead splits power neatly between both socks—clean and efficient.
Micro Alloy-Fibre: a heating technology that evenly distributes heat and prevents hot spots
Dual Powered: designed to integrate seamlessly with your motorcycle's 12V power system. You can also power them with a separate portable KEIS battery for use off the bike.
Water Resistant: designed to withstand the elements using waterproof and durable materials
If you're an all-weather rider, you'll know that the winter months can mostly be unpleasant to ride through. Especially in the UK.
Increased Control:
When your hands are cold, you lose dexterity which can make bike handling difficult. Heated gloves help minimise loss of control
Increased Comfort:
Simply put, being cold is uncomfortable. Heated kit helps make your winter rides that extra bit more enjoyable
Reduced Risk:
Being cold increases your risk of road accidents, as your reaction time and concentration decreases. Being warm on the bike equates to added protection
Flexibility:
Ride without the bulk! Heating gear eliminates the need to wear multiple heavy layers, which can prove uncomfortable when on the bike for longer periods of time
I would recommend anyone who suffers with cold feet whilst riding to buy these socks they work very well. The only problem is they don’t tell you that you need a controller to control the heat or your feet will burn.

Good Quality Product
Does what it says, keeps your feet from freezing. Not noticeably hot like the gloves, but just a comfortable warmth. Either drive directly from the vehicle, a Keis jacket/vest or their own battery.

S302 Heated Socks
Nice oversock to keep your feet warm.
A little expensive but worth it to not have cold feet
I suffer with cold toes in temps lower than 5 deg, tried these on a ride last week where the temp was near 0 deg and my feet were very comfortable indeed.

HEATED SOCKS
Bought for my wife in an agricultural setting as we are outside all day, she loves them - absolute game changer for her, and with the fast charger she gets pretty much a full day of warm feet.

Treid them for the first time today, brilliant, wished I had brought them years ago, expensive but worth it, no more cold feet now.

Follow up to my earlier review
Since I wrote my previous review I have bought the trousers. Only problem is if you connect the socks to the legs of the trousers then the heat level of the socks is controlled by the heat level of the trousers, not always ideal, I find I want the socks on max. The solution is a splitter before the trouser heat controller.

Heated socks have to be the new norm
Over this winter I have had many high mileage rides in temperatures barely above freezing. While the first few hours are OK my feet soon became cold to the point could not feel them. The Keis heated jacket and heated grips made my upper body very warm but my feet started to hurt. So purchased the Keis heated socks and wow, game changer. I keep them on full all the time, feet are warm but not overly hot. The difference in the cold is huge and I can now do 8 hour days without feeling cold at all. The wiring connects to the jacket so all very neat and tidy, to the point you forget you have the socks on! If you are a winter rider and like me suffer from cold feet these are a recommdation.

Really help my feet!
I really like these socks! I don’t have a controller on them so they are on “max’ the whole time (unless I unplug them from my jacket).
I find they keep my feet just right. I find tucking some spare cable back into the top of the sock to avoid accidentally disconnecting them is a good idea.
I hope they last me many years!

Really good, only heated at the bottom so the liners would have been just as good

Makes a tremendous difference
I had pre-emptively bought some socks in medium from infinity motorcycles). I expected them not to fit, but while the small maybe would possibly fit my diminutive size 39 feet a bit more snugly the medium seems fine considering I have another pair of socks underneath, so I've been using them this week. Monday in particular was one hell of a day to test them out! There can be no doubt they make a tremendous difference, and I would argue that at 1 °C it is tantamount to a life-or-death difference. I firmly believe that while protective gear helps you in the event of a crash, being warm and dry goes a long way to preventing a crash in the first place.
