Started running at the age of 49 to introduce movement into my health, became passionate about running not only for physical, but mental health. Enjoy road and trail, enjoy many different distances including some ultra's. Have an issue with wanting all the shoes Potential bias in review 1. I have harsh mechanics 2. I am a neutral runner 3. I have a standard to narrow, accommodating foot shape 4. My left foot turns out slightly (slight toe out), which leads to an awkward flow of my left heel and tends to rub the ground when my mechanics get tired. This leads to some outsoles dying quickly in combination with my harsh overall mechanics. 5. I am a pro level sweat machine. This is one of the reasons I have a good rotation of shoes, I like to let them air out. 6. I started running at an older age, no proper training and my steady pace is in the mid 9 minute per mile range Outsoles I have killed quickly: Altra Torin, Craft Endurance, Hoka Mach series (not X) (all under 200 miles) Outsoles that have lasted: Asics Superblast OG (500 plus miles), Brooks Glycerin 20s (avg 480 miles), Brooks Hyperion Max OG (near 500 Miles). I consider 300 my average target for durability
