I bought them today from jd Kallithea and I placed them in my new fila athletic shoes size 46. As for the construction, it is good and it keeps the foot stable inside the shoes. BUT if you dare and put them on as the packaging instructs you, they won't go in no matter what, they hit your toes incredibly. BUT if you place them upside down, meaning the right one on the left and the left one on the right (according to the shape cut), everything is okay. There is still a slight discomfort, but it feels like a foreign object inside the shoes. I hope I will get used to it, time will tell, otherwise they will end up in the trash. As for the price, it could easily be more affordable.

I bought them for Nike Dunks Low and they were not comfortable at all. They had a sticky surface underneath (the only positive thing was that they smelled really nice) and every time I tried to put my foot in, they pushed forward because they stuck on top and crushed my toes, resulting in incredible pain (get some from Devotion, they are much better)
