One of the lightest athletic shoes I have ever worn. I walk up and down steep hills (12-17% grades) in my neighborhood and these shoes feel like they are a part of my foot. The gel cushions the foot falls very well. I was wearing Gravity Defyers before this for a year so, I got used to the cushioning. These are significantly less money so I took a chance based on many positive reviews here. Glad I  took that chance. I highly recommend these shoes at least for serious walking. I would imagine they'd be excellent for running too, if I may be so bold to say.
