Answers for your questions

1I work in the food industry where temperatures can be as low as –30°C, what can I do to combat the cold?

It is imperative to wear woollen socks. Choose the model depending on the temperature. We also recommend that you insulate the shoe by wearing a thermal insole with wool top to provide warmth and an aluminium coated film sole to create a barrier against the cold. For more information, go to our page dedicated to the thermal range.

2My feet get too hot

This common problem is due to sweating and can be improved by wearing Coolmax® socks. A Coolmax® sock dries much quicker than a 100% cotton sock and prevents transmission of humidity to the skin. In fact, it’s the rubbing of the humid skin in the shoe that causes heating.

3My shoes smell sweaty

In closed shoes, particularly safety shoes, it is important to change your socks very regularly and maintain perfect foot hygiene. Next, the best thing is to treat the inner lining of the shoe with 610 deodorant spray, which creates and maintains a healthy environment. This spray can also be used in helmets, gloves, etc. In addition to this treatment, we recommend regularly changing the insole. This insole can be replaced by an insole treated with S3F® which, because of its exclusive treatment, prevents unpleasant odours.

4How do you combat athlete’s foot?

To prevent athlete’s foot and other skin lesions (fungal infections): - We recommend thoroughly drying the feet, particularly between the toes. - In the case of heavy sweating, we also recommend wearing socks made of Coolmax®, a fibre that dries much quicker than cotton. - It is best not to walk with bare feet in common areas, such as changing rooms, to prevent becoming contaminated and contaminating others. JLF PRO products are often combined with antifungal medical treatments.

5I frequently get blisters on my feet and pain at the end of my toes

It is important to wear a shoe appropriate for your activity, to properly position the foot towards the rear of the shoe and to re-lace your shoes every 2 hours. This prevents the foot from sliding in the shoe which limits rubbing, the cause of blisters. Ideally, choose self-locking laces which automatically adjust to the volume of the foot throughout the day.

6I have back pain

You walk a lot or you work in a static position… And your back aches at the end of the day? Depending on the workstation, the feet are stressed in different ways. Numerous kilometres of walking can cause multiple shocks to the heel. In addition to the shoes' insoles, shock-absorbing insoles may sometimes be necessary to increase the shock absorption of the shoe. In all cases, it is important to maintain an appropriate posture for the working environment.

7I have pain in my heel

There can be many reasons but this is often caused by a heel spur. This is a bony growth in the heel that can cause inflammation. To prevent this heel pain, we recommend our special heel cup for heel spurs which will reduce pain by limiting the pressure on the spur.

8I work on hot surfaces (tarmac, metallurgy, near furnaces, etc.) and the bottom of my feet are hot

The best solution is to insulate the foot with a Céra insole which reduces the heat coming from the ground. In addition, and in the case of heavy sweating, we recommend wearing fast-drying socks containing Coolmax®.
