I use CLIMFEET insoles during my training sessions and my craziest sporting challenges! This was the case during the Ultra Run Raramuri in April 2022: a 190 km race in the Canyons of Mexico. I was able to wear them on the warm side at night and on the cold side during the day. Whether you're an amateur or a professional, I fully recommend them!

Your insoles were a great help during a very complicated period when my erythermalgia was getting worse and, on top of that, I had developed allodynia in my feet. I couldn't stand any more insoles (leather/synthetic), and it was yours that stayed with me for over 4 months and still do! Thank you so much.

For me Climfeet is an air conditioner 😎 for sweaty feet in summer and also a heater that warms up during military ceremonies, sports and my winter activities in Font Romeu in the snow: Snowshoeing is an activity where I've never frozen my feet so much!!! Because when you're walking, you have less venous return, whereas when you're running, you really have to be running at -15°C in the snow to get cold. The same goes for cycling !!!!

I used the insoles for cycling in winter, and for running during training in hot weather. In each situation, I didn't feel any discomfort or heaviness. On the contrary, they made my stride and pedaling easier, complementing the orthopedic inserts. Bluffing to test and wear!

Suffering from Raynaud's disease since early childhood, I've tried everything to protect my feet from the cold (electric insoles, wool...) but nothing works. CLIMFEET gives me thermal comfort and total freedom of movement: I never leave them in winter!
