I like them but they wouldn't agree with my feet because there's too much of a heel and the elastic in the sides wouldn't be enough for support for me .
I like the Tessa boot and the Camilla (more jodhpur boot style)
If someone wears non-leather for preference , they are pretty good (though they're ££ ) .
I tend to buy M&S non leather , they do half sizes but I'll mosey on over to the RocketDog site
