Heated socks are an absolute premium product and you will enjoy them for a very long time.
This makes it all the more important to choose the right sock in the right size. Please read through the most important questions and answers in the Bergfritz Lenz sock guide. If you can't find an answer, please contact us (info@bergfritz.ch). We are really happy to help you and know the products inside out.
Which heating socks does Bergfritz recommend for skiing?
The classic Lenz heating sock for skiing is the 5.1 model.
The Lenz 5.1 is also available in a SLIM version. We recommend the SLIM version for men and women with a rather narrow footbed.
If you have adapted or very tight-fitting ski boots, the 6.1 model may also be a good alternative for you. Thanks to the high proportion of merino wool, these are extremely thin in volume.
What is special about the Lenz 6.1? Is it the latest model?
Customers often want to buy the Lenz 6.1 because they think it is simply the latest and greatest model.
In reality, however, the 6.1 is simply an alternative model with a slightly different area of application.
The Lenz 6.1 is a compression sock. We recommend it to ambitious athletes. This pair of socks is also often worn in the Ski World Cup and in ski racing.
Compression socks such as the Lenz 6.1 exert a higher ambient pressure on the muscles. The light pressure exerted on the muscles by the sports compression socks causes the muscles surrounding the artery to relax because they have to exert less pressure themselves. These socks can therefore also be slightly performance-enhancing.
Which heating socks does Bergfritz recommend for riding, hunting or walking your beloved four-legged friend?
The most popular here is the slightly cheaper entry-level model 4.1 from Lenz. Due to the different knitting pattern, however, the 4.1 feels slightly wider.
Why are the heated socks tight?
To ensure perfect heating performance and a cozy, warm feeling, the heating socks should fit snugly. This is particularly important in ski boots so that there are no annoying creases in the socks.
I like to wear the socks a little wider. What do you think?
In ski boots, it's important to wear tight-fitting socks. For other sports or activities and depending on the footwear, this is sometimes less important. We recommend the Lenz 4.1 (but this is also rather tight-fitting). However, the different knitting pattern makes the 4.1 feel a little wider.
Which Lenz size is right for me?
Choose the size that you actually wear. The socks also have elastane in the footbed for the length and therefore adapt to your individual foot shape and length.
In the rare case that you do need a larger or smaller version, it is very easy to exchange them with us. Please note the following information:
We are happy if you decide on a size when you place your order and try it on carefully when you receive it. If the size does not fit, simply send us a short email and tell us which size you would like.
You will then receive the desired size the next working day and a prepaid return label for the unsuitable item. You can then return the exchange item to the post office free of charge.
Please also note the Bergfritz Fairness Program, which regulates the handling of returns.
Lenz heated socks have a merino wool content. Is that really an advantage?
Yes, merino wool has some real advantages:
- The wool is very cuddly and does not scratch and has many advantages, especially for functional underwear
- Insulates particularly well against the cold
- Transports moisture
- Merino wool is particularly light
Which Lenz battery is right for me? rcB1200 or rcB1800?
Lenz offers its battery in two performance levels: rcB1200 and rcB1800. The rcB1800 has a 50% longer power duration than the rcB1200.
For a normal day's skiing with a nice lunch in a warm mountain restaurant, the rcB1200 is always good enough.
For long days of skiing, for touring or even if there are only limited charging options for multi-day tours, we strongly recommend the rcB1800 battery.
Compared to the already high total price of the Lenz heating socks, the extra charge for the rcB1800 is relatively manageable or only around CHF 30 at Bergfritz. We think this is often a good investment, because this battery should still be doing its job in years to come.
Should I buy the rcB1200 with or without Bluetooth?
The rcB1200 is available with or without Bluetooth. With the Bluetooth function, you can monitor and control the temperature of your heated sock at any time via an app on your cell phone.
At Bergfritz, we thought for a long time that this was just another funny marketing gimmick and would hardly bring any benefits in practice. Nobody is going to control the temperature on the chairlift via their cell phone. But far from it - at the latest when we were playing cards in the mountain restaurant, we realized how convenient it can be to control the temperature via cell phone. Conclusion: Bluetooth is not necessary - but it can still be a nice gadget.
Can I wash Lenz heated socks?
Yes, you can easily wash your socks (without battery) in the washing bag provided at 30° on a gentle cycle. You should then air dry the socks.
Hand washing is not suitable as you could damage the heating elements.
You can find the official washing instructions from Lenz here.
How does the Lenz Heat app work and what do I need to know?
If you opt for the Bluetooth battery(rcB1200 with Bluetooth or rcB1800 with Bluetooth), you can also control the heating function via your smartphone.
You can find more information about the app here. If your question has not been answered, we will be happy to help you.
Are Lenz heating socks worth the money?
In the end, everyone has to decide for themselves.
Lenz heated socks are really expensive. But honestly, you really do get the very best product on the market.
Otherwise, our Bergfritz heating socks are also a good and clearly cheaper alternative for you. Especially for occasional athletes or anyone for whom "just good" is enough, this is an option.
