So I've often seen threads on this topic over the years and would like to share that this year I think i've found some www.clarks.co.uk/p/26106214
i've not been a big fan of clarks for a while now but have to say I'm impressed with their online ordering - no delivery charges, ordered sunday afternoon and arrived Tuesday afternoon.
They are comfy, pretty and colourful and lots of adjustments for when feet swell up in the heat!
