I discovered Birkenstocks last summer and have a pair of Arizonas in navy and a pair of Madrids in white patent. Love them both. Both regular fit. I tried Arizonas in narrow but they felt too narrow - my little toe was on the ridge. However, my regular fit Arizonas have developed a crease on the leather between the two straps on the inside of the sandal. There's a small split at the top of each crease too. Does anyone else have this? I'm wondering if it means they're too wide if this has happened. And maybe I should persevere with the narrow fit (though I would normally go for a wide fit in other shoes). Will the narrow fit give at all?
Any advice?
