Where can I buy wide fitting girls' sandals?

[Sauvignonblanket]

Help lovely Mumsnetters! I normally get children's sandals from Clark's but this year 5yo DD needs 13.5 G or possibly H fitting sandals and they don't have any in stock.

I was looking for something like this with a sole that's quite thick and supported:

Nothing on Startrite, Next and M&S. Where else should I look?

Thank you!

Is there a particular reason you want thick and ‘supportive’ soles? Unless there’s a medically diagnosed reason to need them, children’s feet are far better off in flexible thin soles that allow them to feel the ground and their feet to develop.

Have a look on the Happy Little Soles website

Ds (H fitting feet with very high instep) had Ecco, Geox or Ricosta sandals at that age.

Does it have to be sandals? My children have really wide feet and I got them some Crocs for the summer.

Thank you! She has her heart set on sandals....and maybe I meant something about the soles supporting arches and got the phrasing wrong, I thought that's what I should be aiming for?

The Saltwater surfer style kids sandal might be an option - they are wider fitting than the swimmer style. ££ but very hard wearing and comfy.

Mine both have wide feet and Birkenstocks fit well. They have ones with backs.

Thank you everyone - I'm trying Geox but lots of other possibilities which I'm sure she'll need at some point.
