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.
Bought the lead to check whether the fault was with the lead or the jacket, unfortunately its not the jacket, so I have now an expensive non-heated jacket.
The fast charger is good value. It does away with using iphone chargers etc and is a dedicated speedier way to charge my various batteries. Well recommend for the price. Good efficient delivery as well
Decided to hold out for the new stock of 601 ultraflex and happy I did, had hoped to get it in time for a recent trip but it wasn't to be, and a very cold few days away made me glad it would at least be waiting when i got back. Fast communication,
very smart and stylish, appears well made, very easy to fit leads to bike. Decided after watching reviews that I needed a medium to achieve a snug fit and get maximum effect, but at 6ft and 14.5st I worried it would be too tight and changed my mind, ordering large at last minute. Mistake! I wish I'd stuck to my first choice of medium, test rode this weekend, not particularly cold day but I had to be on high setting to feel any heat and never got hot enough to have to turn it down. At high speed the wind presses the jacket against your chest and you immediately feel the difference, so I imagine a snug fit would have been understandably so much more effective, but without fitting to the bike and test riding with your own gear it's always going to be hard to gauge. Fit is a personal preference and It's a fine line between snug but comfortable and simply to small. I spent ages watching and reading reviews and still got it wrong. Can't knock the kit, just my size choice.
After years I've refused to buy any of the heated gear, I've decided to give it a try. So I've bought the heated gloves from Keis. I must say that I'm very impressed with them. Quality is great, used them only on the low power and they work great. My daily ride is 2 hours + on motorway and through London per way, and they work perfectly.. no more cold hands at all!!! Fully recommend to
My first experience of heated clothing - initial use suggested that so far the quality and performance is very good but waiting for winter temperatures for a clear indication of performance.
Got the j801 puffer jacket and the new improved 5000mah battery while it was on offer and the jacket is fantastic i use the batter or my other keis apparel and its far better than the old one id highly recommend both
Well made and very warm. Retains heat well. All wiring integral and plugs into trousers socks and gloves with all connections built in. Connects to bike battery with connection cable on the box. Lots of movement flexibility around shoulders and arms. Great as a liner to bike jacket. Smart on its own as fleece off the bike. Expensive but quality. Three setting with controller also in the box.
They seem good. Nice and thin so can use them under my regular gloves. I've got those mits for motor bloke as well. Nice that they come with connectors for bike battery. Hope they make a difference this winter
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. Adaptable power options allow them to run from a 12V vehicle supply for on-bike use or from optional KEIS portable batteries stored in discreet leg pockets for off-bike warmth. 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
Well made and very warm. Plugs into trousers of same make.

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.
