Here's a festive cushion I saw at the mall.
So have you heard about the Allbird? It is a knit wool loafer made of wool and castor bean oil that is all the rage at least in California according to my sister who lives there. It has minimal styling and comes as a runner or a lounger, costing US$95. It does look very comfortable in that link I followed.
In fact my sister did visit the Allbird store and was not impressed. The shoes reminded her of bedroom slippers, very comfortable but no support.
