My shoe story went an interesting direction. My SpeedCross was starting to kill my Achilles, as mentioned above. Too much drop. I had the Vivo's, but first tried to remedy my actual issue on the road. So, Kinvara to the rescue (4mm drop road shoe). Love them! But more trails over the last couple of months and... Speedcrosses are now history. Toe nails and Achilles are immensely glad! Toe nails started getting issues as soon as the runs started getting longer. So, I got the Sense Pros and absolutely love them. Went in to get the Peregrines, actually, but walked out with Sense Pro's. I just preferred the flatter side to side feeling of the Pro's. The Peregrines felt much more shaped and "supportive", where the SP's felt open and flat. Loved them from the first k! Zero issues thusfar. BTW, Koei, where did you find Mantras around here? Yes, I still have the Trail Freaks, but will get into them once I have put this idiot marathon decision behind me. Don't want to run any risks at this late stage of that little fight... Whilst on this - not sure how often dee_biker frequents this thread, but know him and a couple of things on his behalf: He does not run long distances at this stage, from memory longest was a 15k. Also, I cannot recall him having gone too hectic over rocks, but where he does, he says you learn to look - obviously you do feel the sharp rocks through vivo's or vibrams (his other joy in life!) BUT - as a guy that completed Comrades a number of times and stopped running due to persistent injuries, for the first time he is now running without an injury, worry free, just go. We talked about it just the other day and the "bonus" he had was having stopped completely for a number (3 to 4) of years. When he restarted now, he started with the Vivo, so he was forced to run correctly and the correct muscles strengthened as a result. From a guy who was a severe over pronator, with special inserts in his shoes and all, he is now just running minimal shoes - without any issues, where previously he had issues even running with all the inserts, protection, stabilization and whatever else. Fast and injury free... I think he'd like a very low drop shoe for longer runs where he might need more protection. And when I was shopping around, he got the itch. But simply could not find a shoe that is in any way as comfortable as the vivo's. Last time I checked, he's stopped looking and even got the 5-fingers out for road runs!
