These are the best running shoes I have ever owned. I have run in Nike, New Balance, Brooks, Adidas, and others not even worth mentioning. I started using these shoes many models ago, about fifteen years ago. Asics keeps improving the shoe with each new model. They are lightweight and very durable. They feel comfortable, but provide plenty of support so my feet do not over-pronate. I tend to drag my heels a bit, but the sole near the heals do not wear out excessively in comparison with the rest of the sole. I run on asphalt and concrete and the gel provides plenty of cushioning while maintaining my foot stable. I highly recommend the Kayano.
