When I was looking at purchasing HPX shoes, I was doing a lot of looking. I had my eyes set on 3 different ones. Hammer's newest model, Storm's newest, and the Pyramid. I really didn't know what all the other soles and heels would do for me and didn't really see a need for them. If I have to buy, or want to, in the future I'll just eat the cost of what it is. I see they really aren't much different price wise before you have discounts from websites and the lack of extra's, I just hope they hold up over time and do me well.
