Birkenstock London is GARBAGE, don’t buy to the hype. Aesthetically it looks great and minimal, but the shoe is itself is so trash to wear Terrible function 1. the sizing is so big, I’m a size 45 true to size and I had to get a size 43 since it fit larger. ( I’m lucky I went to a store and tried some on) 2. The classic footbed is NOT for everyone, you’re taking a BIG risk it’s supposed to break in and mold into your foot but it’s not worth it. My shoes broke in uneven on one of my shoes and it gave me pain below the toe. (Which is odd) all this did what make my shoe worse to wear It’s a risk to even buy Birkenstocks in the first place, everyone’s foot is unique, like, for flat footed people, we can’t just make a shoe with a fixed, less flexible footbed that just forces someone’s foot to conform to a certain standard. It’s uncomfortable and not reliable, There’s a BIG need for flexibility in the foot bed, this cork material needs to stop, like cmon especially in the Londons but thats just my opinion, Birkenstock needs to upgrade cuz this is so disappointing oh my GOD
