Yes they are overpriced.  But you have to consider that you are buying 2 pair-one for you and one for someone in need.  That makes it a worthwile price I think.

I tried these on at nordstroms.  I also recomend trying them on before you buy.  I bought these to wear without socks and had to get 1.5 sizes smaller than my regular athletic shoes with socks.

The fit is snug around the foot and the shoe is light so it feels like wearing slippers.  I have very flat feet and wear athletic shoes that correct my flat foot with a lot of arch support and stability so for me these shoes are too flimsy to wear all the time.  I wear them to work where I sit and if I am running to the store or somewhere quick.  But I would not wear them if I would be walking all day.
