Any Toddler Brands Wellingtons WIDE?

[SKLC]

I have a 1.5y old he has a 3.5 roughly size foot (he has 3.5 Clarks and still some space in the front)

He is quite slim, but think he has inherited the wide ankles in my side of the family. I also can't wear most boots unless they have stretchy material (My dads side of the family has just cursed us with wide chunky feet)

So just wondering what brands do wide fit, I went to Clarks site but only saw Wellingtons from size 4 up and 3.5 is already on the bigger side.

Any other suggestions so I don't keep buying boots for him? I have 2 pairs already, one is 3.5 (Aigle), another is 4 (George ASDA?) and with both his feet just get jammed in sideways and no amount of effort will get them on.

(need them for nursery)

Bogs wellies. Had the exact same issue with DS1 and they were the only thing we could get on, as they open almost fully at the ankle via velcro at the back. They aren’t enough coverage for full blown wading in deep puddles. But they are completely fine for splashing in puddles/walking in the rain to nursery etc.
