It doesn’t stay connected to my app. It’s very hard to change. The app is always being updated and you have to do something new they need to make the app do what it’s supposed to do. ### 3/5 — Only one set of batteries allowed *2025-01-11* Needs to have the ability to add more than one pair of batteries, like the Therm-ic app that also has more functionality. I need two sets of batteries on colder days. ### 1/5 — Gimmick *2024-01-19, version 3.0.2* App sucks and is a pain to use. Battery does not last long and does not keep feet warm. ### 1/5 — Flaky USB connection *2023-12-23, version 3.0.2* Please update your app to the modern times. I’m tired of spending 20min troubleshooting connection issues before skiing, having to reset each device, it’s not worth the money. I wish there was an alternative product. ### 1/5 — Keeps disconnecting *2023-12-13, version 3.0.1* My heat heaters keep disconnecting from the app on the phone. Pretty frustrating. I hope there is a fix soon! Love my boots, but this problem is aggravating ### 1/5 — New app *2023-12-11, version 3.0.1* The app update is terrible. It doesn’t stay connected. The old version was solid and always worked. We have 4 sets of boots / phones with heaters. Same issue with everyone’s. ### 1/5 — Plug broke *2023-03-21, version 2.11* The point at which the plug enters the battery just broke off. ### 1/5 — Heaters won’t stay connected *2023-01-07, version 2.11* Heaters won’t stay connected and the app crashes when I try to fix it ### 4/5 — UI Still awkward *2022-12-18, version 7* As I mentioned in a review 2 years ago some of the buttons on the main screen overlap and are unusable. How about reducing the space consumed by the inactive logo at the top to make room for important functional parts? I needed to replace one battery and found it impossible to do so, had to delete the app and start anew. Also wish each battery could have separate control for heat level. One of my original upper elements was replaced with a sole part and I now have to settle for a balance where one is too warm and the other too cool. Overall it mostly does the job but still needs some improvements. ### 1/5 — Never connects. *2022-02-04, version 7* Brand new and the app never connects to the batteries. Very frustrating. ## Most critical reviews (10 lowest-rated) ### 1/5 — Not Working *2026-01-10, version 3.0.9* Heat is on full but no heat in boot. Battery is not discharging. Pulling these boots on and taking them off is incredibly painful and time consuming. ### 1/5 — Heaters that don’t really get that hot *2025-12-27, version 3.0.9* My wife and I both bought the 3400’s, so it’s not just a defective pair. We both agree they just don’t get anywhere warm enough that they make a difference. Surefoot liners are amazing and worth the extra $$$, but these heaters have been a disappointment. Also, the instructions seem outdated, and the UX in the App Store doesn’t match the actual app UX. Renaming the heaters to something unique doesn’t stay, you also have to rename them everytime you turn them on, which is an idiotic experience. ### 1/5 — Unreliable *2025-12-23, version 3.0.9* Have had these heaters for about ten ski days and they were starting to go in me and now won't turn on. $400 worth of garbage. My last pair lasted me 7 years. Different brand. ### 1/5 — Batteries won't charge *2025-03-15, version 3.0.8* The instructions do not work. One battery will not charge and neither will connect to Bluetooth. There is no menu at all. ### 1/5 — Not Turning on *2025-03-08, version 3.0.8* I just bought it never really worked. It’s a huge waste of money. ### 1/5 — Overpriced, fragile, poor BT connectivity *2025-01-25, version 3.0.7* Bluetooth connection is hard to pair reliably and drops. Supplied charge cable lasted one season. Battery packs lasted three seasons - replacement packs are $425 - would not buy again. ### 1/5 — Great boots awful app *2024-12-13, version 3.0.6* Buggy app has constant issues connecting. App continually says Bluetooth is disabled when it is not. Deleting and re-downloading the app does not resolve. Neither does resetting the batteries. Do not recommend. ### 1/5 — App is bugged *2024-02-17, version 3.0.3* I’v head Surefoot heaters for years and this new app is buggy. It only connects consistently with one battery. I can no longer control the heat separately. I am not the only one having issues with the battery connection since this app change. ### 1/5 — Warmth not great *2024-02-10, version 3.0.3* Batteries on 3 and feet still cold at 25 degrees. Great fit on the boot just not great heaters for the cost. ### 1/5 — Quirky. Batteries keep disconnecting and even after replacement having same issue *2024-02-06, version 3.0.3* Not impressed for the money most of the time still have cold feet. Or at least one. ## Most praised reviews (10 highest-rated) ### 5/5 — Excellent investment *2025-12-07, version 3.0.9* Glad I have these. It’s freezing and I’d be in no shape to ski to without these. I was hesitant to buy them due to the cost but glad I did. My feet are warm, dry and comfortable. Nothing ends a day faster than the boot blues. ### 5/5 — Easy and Dependable *2025-02-08, version 3.0.7* Have used for multiple days straight and love it. Set it and forget it. Cool that you can rename the batteries. Mine are Starsky and Hutch. Highly recommend. ### 5/5 — Warm & comfy *2025-01-26, version 3.0.7* These warmers allow me to ski all day without cold toes. ### 5/5 — Best boots *2025-01-24, version 3.0.7* I am on my second pair. Looking forward to BOA next year ### 5/5 — My invisible boots *2024-11-19, version 3.0.6* My Atomics gave me an aggressive stance and edged well but were slightly uncomfortable by the end of the day. OTOH, I forget that I have the Surefoot boots on because they are so comfortable. The neatly integrated liner heater is a good idea and the Killington SF shop stood behind the product (thx Chuck) when I had an issue with one. Good product and good service. ### 5/5 — Sure foot is best *2024-01-10* I love sure foot 👍👍👍👍👍 ### 5/5 — Love it! *2023-12-17, version 3.0.2* I love this app. So simple and easy to use. ### 5/5 — Susan Ansley *2023-01-29, version 2.11* Just skied 5 fabulous days 🦣every day the fit became better ⛷🥰any recommendations to help me 💕💕love my heaters 19* on high 25 * med heat perfect😎 ### 5/5 — Idiot proof app *2022-12-31, version 2.11* Great simple app, wish they would let you connect 4 batteries ### 5/5 — Simple but effective *2022-12-13, version 7* Simple app but it does all that’s necessary. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
