At the end of the day you're taking style advice from women who wear Clark's and M&S.
Speak for yourself.
First ones are very borderline, too smooth as AnyFucker says and the front/foot bit is too long, top too narrow, heel neither one thing or the other.
Second ones are better but stupidly overpriced. You can definitely find some just like those, but better, for a lot less.
I like Dune but find you have to try their boots on to really judge. I ordered what I thought were some low heeled bootie things from there and when they arrived they were shiny boats with a Mum boot heel. Nope.
Get into a store if you can.
