Does anyone know of summer sandal shoe things that you could do longish walks on uneven surfaces (e.g. hills) that are covered to some extent so not disaster if rains. Want to wear them with casual summer clothes skirts and jeans/crops. Only seem to be able to find things like those white criss-cross things currently in Clarks ad campaign. Do not want to look like child or elderly person - want something a bit funky but practical too. Would love any ideas - like to get nice shoes as would cheer up following upsetting pre-summer no clothes shopping trip. Ta v much
