I love the solid sole - you can wear them to run tot he mail box or the drive through. Im sure its really meant for phones using USB C and not laptops, even though it explicitly says MacBook. These are such soft and cozy jammies! These shoes squeak LOUDLY when I walk. The shoes have been on a shoe stretcher since the purchase so I will not know if that worked until I walk around in them for a few days before the event, April 5th. I bought another without hesitation. I?m 5?4? and weigh 155lbs. Fabulous shoes. I bought them based on Clarks popularity years ago. Glad I did, they are a perfect fit.
