Great minds think alike; that's how I manage most of my clothes and my sports shoes.

Being diabetic I try to keep a close eye on my feet. I have one pair of "good" town/shopping trainers; two pair that I rotate daily for at home wear, and one grungy pair that is worn for yard work, painting, etc.

a good thing to do with all items in your home..rotating out anything that is old and crappy when newer arrives in.

and esp food..rotate out food quickly..through your belly

We have been a "one in, one out" family for YEARS now!

I use the same hierarchy system for white t-shirts. I wear them a lot with cardigans and misc layered outfits, and they can get dingy pretty fast.

I use a similar system for my exercise/walking shoes. When the tread starts to wear thin, I go out and buy a new pair and the old pair gets demoted to dog walking shoes, the old dog walking shoes get demoted to yard work status, and the old yard work shoes go bye-bye.
