No blisters when worn right out of the box. The footbed feels cushy and has a bit of arch support. I bought this as a gag gift for my wife because she loves cats. Not huge on bass if you are looking for that big bass sound it really doesnt have it but it is a loud little speaker. But after reading another review on them I decided to tap each one 5 times to be able to pair to 2 devices. For the price it?s a must have! There is something about this shoe that makes it work well for my foot even when walking fast. Wes Anderson?s status as an American auteur and cinema icon are forever solidified with his third motion picture: The Royal Tenenbaums. My cats hair was sticky. I have been wearing these for years, they never disappoint.
