I'm going to California this summer and I want some sandals that will be really comfortable, can be worn with most things but don't look too frumpy. Was looking at [[http://www.shoetique.co.uk/womens-c1/sandals-c8/fitflop-fitflop-sandals-fitflop-via-bar-urban-white-p1323 these]] and [[http://www.birkenstockuksandals.co.uk/birkenstock-milano-sandals-803-silver-p-985.html these]] Any thoughts on which is better? Thanks
