Hey hazi, if the boots are open-toes, go with your normal size 8. When it comes to boots, it’s not so much the length of the boot itself that makes them “smaller” – it’s the way the manufacturers design the upper of the boot (i.e., the part that covers the toes, top, sides and back of the foot). In my experience, size up in Pleasers and with Ellie’s it can be a crapshoot because theirs tend to run wider and looser. That being said, with Pleasers it can be a crapshoot as well: I myself size up, but I’ve plenty of customers that can wear their normal open-toes size. They will stretch and break in as you wear them.
Bottom line? Best to go into an exotic wear boutique and try a pair on to see what works for you because everyone is different.
