Rhyton sneakers

[strawberry17]

Hi all, can you recommend sizing for the women's Rhyton? I sized down for the bee Ace (for women) and even though I'm usually a 39, I've bought 38.5 and 39.5 in Gucci depending on the form.

I'm interested in the wave design to purchase online but unsure if sizing varies by design, as on different retailers (NM, Bloomies, MyTheresa) I've seen different advice for different iterations. For example Bloomies says true to size, MyTheresa says size down half a size, and elsewhere I saw it says it is a tight fit.

Those of you that own or have tried them on, what's the deal? Thanks!

have anyone experienced return with mytheresa recently?
did they return full amount or take off duty tax off?

Please Avoid Mytheresa!!
I bought a Roger Vivier shoes, lost by DHL during delivery, Mytheresa had bad customer service, irresponsible by not following up the matter + being a liar when they said DHL cannot do anything, so do them. The fact that when i tried to contact DHL by myself, there was no history of complaint/investigation ever made by Mytheresa.
€440 + express Signatured international shipping cost ALL GONE FOR NOTHING!

Don’t wait until you lose your money. Better avoid them, seriously. It’s a pure experience by myself.
