Not only are these very comfortable on cement floors, but, as a Special Education teacher, I enjoy finding ways to judge the attention level of students. These, and my other black and white "red heart" Birki's, do the job! Not only do my students comment on them, other teenagers in the school notice and tell me how much they enjoy my shoes. Not the traditional tennis shoes, they are a statement that we are each individuals and get to choose our clothing accordingly. Oh, and I am 61 years old, which is proof that we are, indeed, forever young.
