Fitflops  are THE most comfortable shoe. I work (walking & standing) on a concrete  surface for 8-10 hours a day and this is the only shoe that I still feel like going for a walk after work! They provide the arch support I need, cushion my heels and the balls of my feet and most importantly they stay on my feet no matter how fast I walk (or run) up the stairs. I already have the black walkstar 3 and am so pleased with the brown. LOVE the color!!!! Ordering from Amazon was great, they arrived on time and I am very pleased. Can't wait to try more styles. :)
