I have very wide calves (57 cm) and I have not been able to wear wellies for many years. When I read the measurements of your wellies I was a little sceptical, but went ahead and ordered, half expecting to have to send them back. However, to my delight, not only do they fit but there is room for liners and my jeans inside them. They look lovely and come well up my calves. I am looking forward to some muddy Winter walks. Ordering was easy and delivery was fast. Just delighted!
