Anyone seen anything that will help in my quest? I'm looking for shoes I can wear to and from the beach on holiday. I have lived in Birkies in the past for this but have Achilles' tendon problems so have been told that total flats are out and that a heel strap is best. Also, I don't do toe posts. Budget up to £80 but would prefer cheapish as sand and sea will probably take their toll.
I love a wedge if that helps? 
for anyone who can offer any options!
