Isotoner Slippers Size NWT marked 8.5 (fit is smaller) More like 7.5-8

Reposhing this item I purchased from @kyly1. Just bought these, they do not fit like that size- are smaller. The inner fur is very thick. My FEET are this size, slippers are not but Posh won’t allow return. Shoes here should be returnable. I’d say more like 7 1/2 Brand new Isotoners, with tags. Please make reasonable offer! Thanks
