MediPedsWomen's Diabetic Crew Socks with Non-Binding Top and Cushion Sole 4 Pairs

I wear a 6 shoe, usually a 9/11 sock. These are sized 8/10 or 10/13. How do they fit according to your shoe size

These are on the thick side yes?

Are there knots at the end of the seams?

How much padding on the soal???
