They dont feel light duty, Im quite impressed, especially for the price. Loved these heels. I held them against a size 3 vans. and 1 frame actually fell on a person, resulting in injury. VERY disappointed in this poor quality product. Included with my purchased earbuds was a card promising a 20 dollar Amazon gift card for providing a review. Feel very comfortable. You can?t just go to a store and buy Clogs where we live. will work great for car top luggage, protects my glass top. Someone with bigger ears may find them uncomfortable.
