I'm an easy runner who does about 5-10,000 runs a week in nice weather (in Hong Kong where I live it's about 70% of the year). So far I find them comfortable and thanks to their firmer support I can run faster while protecting my feet and also unlike ultra light shoes. But obviously as it's quite expensive I'm not sure if it's really worth the money or not for a casual runner like me but they're still in great condition after over a year so I have no complaints.
