I wanted shoes I could wear to work on hot days and either dress up or dress down. These sit in the ear canal and block most of the outside noise allowing her to take advantage of her music and videos. 5 hours and they let so much wind noise in and if one falls out while doing 20mph you will never see it again. As well, it has a hollow in the center that is a good place to cradle the family jewels. I used to wear Teva leather sandals all the time, but these are lighter and even more comfortable. For $35, I expect it to work. With the Ascher rechargeable bike lights I feel confident that not only will I see whats ahead of me but - maybe more important - vehicles and pedestrians will see me well before they get near. When I took it out of the package parts were bent so that they couldnt fit together. Highly recommended for everyone! Hurts to use it.
