These are ok. Very soft and comfortable with no pinching, blistering, painful pressure points etc. Best thing about them is their price and the fact that they support a worthy cause. The cons are that they are pretty shapeless - just long ovals, like two small ciabattas, extremely flat at the footbed and offer absolutely no arch support. I'm a true US 8 in length, and between narrow and medium width. I bought the size 8 and my feet are pretty much swimming in them, though to their credit, they somehow manage to stay on when I walk. I'll have to pop in some insoles for a better fit and arch support. Not too bummed out, but not over the moon with this purchase.
