In my quest for the perfect size, I have several pairs of J/Slides kicks in my closet! These are Cognac newbuck waterproof and shearling lined, dual zip platform ankle booties. Size 8 and runs true to size, but if you want to wear these with a thick sock, size 8.5 would be better. However, they are so warm and cozy a thin sock works. I tested these out for an afternoon, so they are like new. Perfect for running errands in winter, etc. Poppy model.
