Winter Boot for skinny child with giant feet

[tubby1]

Can anyone recommend winter boots for my 11yr old daughter, she has size 6 1/2 feet but has skinny legs. I would prefer she could ride in them and they need to withstand lots of mud. Thanks in advance

I have slightly stick like legs and found tuffa boots best- they have velcro closures to make them neater. large fitting so a six would prob do
