Dearfoams slippers size 9 ladies

ladies size 9 I wear an 8 1/2 but when I needed slippers to slip on just to take the dog out to potty, I bought these, problem, they only came in whole sizes so I sized up --- MISTAKE, I should have gotten the 8. (these were just too big - decision made after I wore them a couple times briefly outside on my driveway) Dearfoams black and grey
