Style & Co silver boots size 8

Bought these silver boots at macys for $60.00 like a month ago and at the time I had 3 pairs of socks on because I was wearing rainboots and so when I tried these on they fit perfect there I go to wear them last week and they are to big I knew it seemed funny that an 8 fit me when I'm a 7 but they are the most amazing boots ever really better then uggs and more comfy then them to also the bottom of the boot is very hard and sturdy so perfect wish they fit cause I hate to even sell them
