I take shoes out of the active rotation between 300-350 miles. I get uneven wear on the outside of my heels, and years ago a podiatrist suggested dumping shoes once that wear pattern was established. I don't know if it makes a difference or not, to be honest, but I appreciated him giving me license to spend more money on my relatively low-cost hobby. ;-)

I usually have two pairs active at a time. I track usage on my running log (although, full disclosure, my log is several months in arrears at the moment -- I have all the info, just haven't entered it into the spreadsheet).

• stability: I wear a neutral shoe.
• cushioning: I'm a maximalist.
• heel-to-toe drop: I'm a traditionalist. I experimented with a pair of Newtons (with lesser heel drop) and liked them until I ramped up mileage. I still wear them once in a while for short warm up runs on the TM at the gym.
• brand: I'm partial to Asics, but not married to them.
• presently using: Asics Gel Cumulus

And that's all I know about shoes.

I seem to get about 2-3 months out of my shoes. But they also get used for hiking and fitness walking. When I deem a pair of shoes not supportive enough to run in, then they become my walking around at work shoes. I rarely wear anything other than athletic shoes. Eventually they rotate into the collection used for gardening. When enough of those accumulate, they go to one of those used shoe recycling collection events.

I've never, ever had a pair of shoes show a wear pattern on the soles. They just lose their internal support and then my knee or hip gets cranky.

I only wear New Balance as I need the wider toe box. I stick with the same model until it becomes obsolete. I've probably purchased at least 10-12 pairs of my current model since it has stayed available for sale for over 2 years now. For awhile, New Balance kept changing their models seemingly every 6 months and it was really annoying. Especially since often the "new and improved" version didn't get along with my feet.

I wear motion control shoes and swap out the provided insole with Pinnacle Powerstep insoles which give me more arch support. It makes my knees happy to have a solid base under my feet.

No running yet this week for me. Too many work meetings. But my legs probably needed some recovery after last week's high miles. Some amount of running will occur tomorrow.

WooHoo! 6.85 miles run/walk this morning. The rain had moved through before I started so it was just overcast and humid. After spending 3 days sitting in meetings, it was delightful to be outside even if the rains had made the mosquitoes come out. Today was all about the mental benefits of running.
