These shoes are by far the best athletic shoes I've purchased in years if not ever! I wear them everywhere.  I'll be honest, I initially bought them b/c of the colors, but am pleasantly surprised by their comfort. I have plantar fascitis in my right foot that I've been undergoing treatment for and these shoes have actually helped in my recovery.  Not to mention my custom orthotics work well with the shoes. And as some of the other reviewers mention, the top of the shoe is open and mesh.  However, I don't plan to wear them out in the snow.  I am contemplating buying them in the other colors available.
