Golden Goose Sneakers https://www.goldengoosers.com/

Same! Even though it's a risky thing for someone, it's my favorite way of purchasing them. That way, I can find vintage or rare sneakers and get them for a reasonable price.
My most recent purchase was a pair of air jordans 1 low. They're a little challenging to get by now that they've become so popular. It's a good thing I found them on a site with several pairs and a great variety.
But what was your last purchase? And from where? I'm curious to find out what websites do you know and use.
