An update: I've just ordered these, the El Naturalista ones that both I and herecomesthesun linked to upthread, but in the natural/tan colour. The shoe looks a bit misshapen in the photos, but the other colours look fine, so hoping it'll be OK.

My aim with this shoe is a summer "go with anything" shoe. Having looked at my clothes I need something to go with neutral chinos/linen trousers, a neutral linen skirt, brown dress, white jeans and a black/floral maxi dress. I hoping these will fit the bill.
