When your dogs are barkin', throw 'em an Acorn. Specifically, the new Women's Acorn Moc. Acorn started an EVA foam cushion and topped it with a memory foam layer to make the most comfortable slipper possible. Many companies would have been satisfied with that, but not Acorn. It knew you'd be reluctant to take these off, so to facilitate all day comfort, Acorn added a moisture wicking liner. The cozy fleece upper tops it all off to create an incredibly comfortable slipper that will keep your feet happy for hours on end.
