These are by far THE best running shoes (or just "shoes") on the market!!!  They are super, super comfortable, supportive and absorb the shock like no other shoe!!!  Take it from me, I have had both of my feet and ankles completely reconstructed due to injury.  I have to wear shoes all the time now, and they have to be good ones.  I can't risk stuctural collapse in my feet or I'll have to have my ankles fused.  I will swear by these shoes!  The tops aren't as durable as I'd like, but the soles and sole stucture will last two years or more depending on use. I still wear my two year old tubes and I just ordered another pair.  You won't be sorry.
