The unit is very comfortable and it muffled all the outside sound which is awesome for gaming. These are primarily meant for audio conference and not for music. Im on cement floors over 8 hours a day, either standing in a spot for awhile or running around A LOT, and these shoes are great! My Moto G4, whenever I have a mail comes in, I get the notification in the phone about 3-5 seconds before it pops on my computer. I could hear kids on the floor commenting about how cool looking these wheels are. never been so satisfied with my purchase at Amazon as I have been with this. They are also mounted on the stud. Fits like a glove ?? really happy with my purchase ???? Thank you so much! Ive even worn them to go to the post office and no one says a word. I stopped after about ten miles to check everything, and it was completely sturdy.
