Land boots are great for casual wear. They are not dressy at all.
I own a pair and i love them. I wear them tucked in my jeans or cargos. I've worn them to watch my kids run cross country.Yes, they have trudged through mud! They clean up nicely. The are also great with minis when you want something more casual.
In fact I brought them with me this weekend, worn under J Brand cargos. They are really comfy of that matters.
I have a pair of distressed black ones, very motorcyle-ish, I wear them mostly with jeans but also leggings, and under cargos too, they are super comfy and I've worn them everywhere from a visit to a farm with the kids to a client presentation
