True; it now looks as though I need to get my shoes a half size longer. Not only do shoe models change; feet change! The last pair of the old Hardrocks I bought up before they disappeared is still brand new, but my toes are pushing the end a bit. I'll try thinner socks, to see if they'll still worker a while longer.

One thing I've noticed is that evidently it's expected that most buyers of running, etc., shoes will replace the insoles provided with the shoe with insoles of their own. This may be fine (I use green Superfeet which have effectively prevented a recurrence of my nasty bout of plantar fasciitis some years back), but it provides a second fitting issue in addition to just the shoes. In other words, just because the New Balance SL-2/Green Superfeet combo works for my weird feet (bunions, hammertoes, extra narrow heels) doesn't mean they will work for anyone else!
