Specifically: buying shoes on the realreal. If you live in nyc and are like me, you’re probably really hard on your shoes. Remove the anxiety of scuffing a new pair of by buying someone’s barely worn ones. You get good quality shoes for a regular price AND you won’t be devastated when you trip up the subway stairs (couldn’t be me!!).
Also, yes, you can get trendy stuff but it’s not that discounted. Do some digging in nice brands that are known for making good shoes.
Pro tip: if you’re looking on depop or similar sites, know your Japanese (JP) or cm shoe size. Sometimes it’s just marked as CM on the tag. This is the size of your shoe in centimeters and is less arbitrary than other sizing systems!
