I purchased these based on the many positive Amazon reviews, and was not disappointed. Extremely lightweight and comfortable for aerobics, step and body combat classes. As others have mentioned, the shoes have quite a wide toebox, so they're good for wide feet/bunions etc. Also pretty much true to size, I bought a 1/2 size bigger than my usual shoe size which I often do for gym shoes and I probably needn't have done so. A good buy!
