This is my second pair of these shoes and I have to say that they hold up really well and are priced very reasonably.  In the winter, I screw hex-headed screws into the soles and run on the trails with them and during the summer I use them for track, street, and trail running.  With speed laces, they make great race shoes for triathlons.  The gel holds up well and the shoes maintain form even after much punishment.  I pronate slightly when I run and rely on these shoes to correct my form without causing discomfort.  In short, these are great multipurpose shoes.
