Dear J'Adior slingback owners, I'm very new in Dior shoe-world and recently I've been looking into getting the J'Adior slingback pumps. I really appreciate some help on the sizing of these 3 below. For your reference, I wear sz 35 in all Valentino rockstud pumps (100mm and 65mm - 1 pair of my 65mm runs about 1/2 sz large on me). Chanel sz 35 slingbacks run a bit too big on me (i had to wear 2 insoles) and the sling is too loose, so I think I may be a sz 34.5 or even 34 for Chanel. I wear 35 in Louboutin patent Pigalle 85mm. Also, are there differences between the 100mm and 65m Dior slingbacks? Thanks so much!!!!
