Hi, I have a nude basic 85mm pumps from JC that I wear to work in size 40 and it’s quite comfortable but does have 1 pressure point at the back of my foot behind ankle. I do last a full day of walking but find can’t last 3 days in a row at work. Like my feet need a rest from the same shape. Now, I am looking for a black pumps for work also. Should I consider one from gianvito rossi 85mm or maybe stick to JC? And should I go for patent or just leather? What do you guys prefers?! Thanks in advance ladies!
