It's like you are some kind of APK Angel...not the girly kind...but the big "Sodom destroying" ones!!!
I do wear vibrams five-fingers some time, but i really like those shoes cause i just plain "regular" running about 20-25 miles a week
I feel like the Ariakes aren't exactly the best shoe to wear in you're running to that extent every week. It's probably the reason why your current ones are so worn out. Try looking at some Asics, New Balance, or Saucony running shoes, and saving your Ariakes for actual parkour training. They'd probably last longer, be more comforting, and be cheaper than going through pairs of Ariakes.
