I have three pairs of Bostons bought over the last five years or so. Black oiled leather bought via Depop, tan suede, and beige leather. The tan suede I got for about £80 in the Urban Outfitters sale, and DP bought me the beige (I think the colour is mocha or something) for my birthday last year, again, heavily discounted somewhere.
I wear them all the time, they look good with chunky socks in spring/autumn as well as with bare feet. For me they have been worth every penny and I can’t wait for the bloody rain to stop so I can get them back out!
I’m also on my second pair of the shearling slipper version - the first pair are still perfect but they smell awful!
