I have very narrow feet and high arches.  It very hard to find shoes that fit and are comfortable.  I took a big chance and ordered shoes on-line!!!  What was I thinking was my response after I hit return on the payment.  However, they arrive quickly and I put them on and have never wanted to take them off.  They fit so well.  I especially like the light weight and coolness of the shoe.
I will never wear another brand.  Also, the cost was incredible low.  I had been looking for shoes in retail stores for weeks and figured I would have to pay around $100.  These cost around $40.  Give them a try.
