Follow this link to get 20% off at shoebuy.com, I believe it does not have restrictions on the type of shoes (hint: Crocs) you can buy. This is not an affiliate link (a.k.a., I am not receiving any referral fee from this).
Shoebuy is having a sale on Crocs, the $10 off discount code is WWMAG. They don’t have many left though, so hurry up if you want to get a pair.
I found Crocs shoes are actually gender-neutral, as you can see from the size definition, e.g., size 4 stands for Women 6/Men 4. I think people choose the Crocs based on color. I just found out they run out of the color I want 🙁
