Sadly nothing special about these insoles. They are thin and go in Your shoes great, but they offer little cushioning. Sadly although a british brand, I wont bother to buy again.
I use both insoles for flats and high heels. They are amazing. Give just enough luxury leather padding without being too thick which can make the shoe too small. A must for flats with the slightly padding at the heel keeps feet feeling so good. Simply the best!
