This is a great looking and performing shoe, perfect for trail walking/running. I purchased it for interval walking, and it would serve this purpose admirably except for a little too much padding in the inner heel area. I'm no expert on running shoes, but from what I have read I assume the extra support on the inner heel is to prevent overpronation, or rolling inward during the stride. Having this extra support in the shoe, however, caused me to develop blisters/calluses in a thin line on the inside of my heel. After wearing the shoes about 4 times, it seems to be a little less painful...perhaps wearing down some. I will definitely try running shoes on in a store to get an idea of how they are made and fit before purchasing online again. That said, these Rykas obviously work for most people (considering the positive feedback), have a great look and seem to be made very well.
