Great product. I use them with safety shoes at work, where I work on my feet for 8 hours. They create a cushion of softness between the foot and the sole, a sort of soft cushion that envelops the entire sole. They ensure comfort, softness, lightness and adaptability with the foot, in the difficult work environment. Having tried different types of insoles over the years, I can certainly say that these are undoubtedly the best ever! I must say that after a while having used them the pain in my legs is gone, I bought a second pair to keep fixed in my work shoes.
