I bought some Saucony Kinveras & liked them so much I bought a second pair. They are light as a feather & remind me of bedroom slippers because the material is soft & very pliable. I've only used them on the dreadmill because I know there will be a big learning curve for my feet & legs. So far, they are extremely comfortable and really facilitate landing on the ball of your foot. I can feel that my calves are working and my entire body flexes more to absorb the landings. Highly recommended if you have a Saucony foot.
