have extensively tried sturdy-ish shoes for similar walks and
clarks freckle face ballet type - not worth money, too soft and utterly destroyed after six months.
hush puppies fountain - new purchase, much sturdier but currently being worn in and ooh they are solid. ow.
birkenstock gizeh - toe post so not for you, but madrids? anyway no problem bringing them out again for a second year.
halflinger clog things - my favourite and desparately uncool but lovely to walk in.
