Okay, so I finally got my hands on these Vionic Uptown loafers after hearing all the hype. Let me tell you - the arch support is LEGIT. Like, my flat feet actually felt hugged by angels. The leather quality? Chef's kiss.
BUT here's the tea: sizing is WILD. I'm normally a solid 7, but these ran so big I could fit my whole thumb behind my heel (not cute). Ended up exchanging for 6.5W and suddenly - perfection! The width was just right for my narrow feet.
Pro tip: If you're between sizes or have wide feet, maybe size down? My friend who's usually 10-11 said they get comically wide as sizes go up. Also that contrasting cream sole? Adorable until you realize it might slip off if you don't get the size exactly right.
Final verdict: When they fit, they're heaven - like walking on supportive little clouds. When they don't? Blister city. Worth playing the exchange game though if you need serious arch support!
