The Finn Comfort line is a real winner no matter which one you choose. This one has a bit of a rocker bottom to the sole which delivers more arch support, but isn't unstable like most rocker bottom shoes on the market today. Most claim to give you better legs, but in reality wearing them all day will tire you out. A good rocker will simply make it easier to walk, and that's exactly what this one does. But if you have any issues with your Achilles you don't want this shoe or any rocker shoe for that matter. It will put too much stress on the tendon. I love these though. They're stable, supportive, and so easy to wear. Great for turf toe. You'll love them too.
