Just look at the pictures. Youll use up less time doing that than looking for an available pad in the gym that probably has hair stuck in the velcro, is dirty and dusty, and has the velcro already worn. I?ve had it installed for about 9 months now and it is holding up great. They had the exact size and style she wanted. I generally wear a size 10. Great product, super easy to install. I was hoping that it would make a seal in my ear canal to block out external noise. The medium fit perfectly. Think the item is perfect what what I needed . I unfortunately missed the return window so I will try to sell privately or give to a friend.
