Bonjour
Moi, je ne sais pas le mot exact francais, mais vous pourriez commencer vos recherches a un “Sports outlet” (Decathlon, par exemple) egalement au studio, ou a la pharmacie.
OK no more teasing. I don’t know the French word for the type of product that you seek. Electrolyte is the same in both languages - minus the acute accent. But it didn’t yield much for me in my brief online search. Naturally you could ask at your studio, a sports equipment outlet or a “pharmacie”.
I am glad that we are on the right track knowing that you are fairly new to the practice. It won’t be long now. Definitely walking long distances in high heels would tighten up the back of your calves significantly. Do you get to stretch them when you get to your destination? My guess is no - because you probably have other things to do when you get there!
If you do have a chance you can do some surreptitious stretching while sitting down. Downward facing dog would be great but not very workplace friendly (depending on your workplace!)
Please say hello to Helene and Christian for me!
Namaste
Gabrielle
