You might never know if it's the comfort or the style of the Acorn Boys' Moc Slipper that's doing it. All you'll know is that your son won't want to take these off ... ever. In fact, between the soft fleece upper and memory foam midsole, you might just want to make sure that you can rent a matching tux for his high school prom. Ok, that's likely an exaggeration, but still, your boy will love the all day comfort that the Acorn Moc brings to the table. Thankfully you won't have to worry too much about foot funk, since Acorn included a moisture wicking liner to help combat just that. So, go ahead, let him wear his slippers all day.
