Camper is a shoe company that makes fun, fashionable sandals (as well as other types of shoes) in a range of sizes for women.
anywhere from 35-41 Eur. the shoes are made wide and comfortable. try them out when u get to madrid. there are 2 right in the city center. one on c/preciados and one on gran via.
my friend has the same problem as she is a also a size 10 and found shoes that looked cute, were comfy and fit her perfectly. the price can range anywhere from 50 eur (or roundabout) to more than 100 eur, although the latter price really pertains to the heavier shoes.
hope this helps girls
