Yeah I see my Vibrams and Adipowers as long term investments, although I don't think the former will last nearly as long as I wear them casually/out and about. Might buy another pair for outside the gym as I much prefer them in summer to flip-flops.
I'd like to think my Oly shoes will see actual Oly lifting at some point but that would require an appropriately equipped gym plus coach. I could have saved money and got Do-Wins or even the PowerPerfect II's, but I just loved how the Adipowers looked so paid the extra lol.
