Please help me find extra wide men's sandals for DS (12)

[sugarbum]

He has size 9 feet, but they are so wide the fitter at Clarks didn't even bother measuring them because she knew they would be bigger than an h fitting. We are off on hols soon. This is the style of sandals he wants. I bought these in mountain warehouse today. They are size 10 and looked really wide to me but although you can adjust the top, they pinch at the sides because the sole isn't wide enough ( sorry that's my badly in need of a manicure feet in there as he won't have photos. I'm a 7e for reference) they fit him lengthwise.
I'm in new territory here as DH has size 9.5 feet that are a standard fit.
Any suggestions? He detests traipsing around shops. I'm super efficient at buying online and returning though 😁

These apparently run very wide:

In my very extensive experience of dealing with wide and high feet (both ds and dh ) you really do have to sit in a shop and just try them on - Cotswold Outdoors or Go Outdoors usually have a big selection. Alas, usually the wide ones are expensive - Meindl or Merrell fit fussy DH.
You could try a size up for a bit more width as you can get away with more length on sandals

Thank you. Will have a look at those

@lululatetotheparty first try wins! Thank goodness because honestly its unbearable taking him to a shop.

Got him the crocs off amazon as I had some credit. Tried both size 9 and a 10 and the 10s are a winner. Lovely photo of my 12 year olds hairy legs there
