If so, I have a question about them. I want to buy a pair online, but I need to know if they open fully at the front, or if the tongue is sewn in.

I googled these to have a look at what they looked like and on some of the reviews

seem to suggest that the tongue is sewn in, otherwise people wouldnt find it so impossible to get their foot into

Yes, that's the conclusion I came to as well. I did email the store, and they told me the boot "opens at the front" but I'm not convinced! It's a pity there are no pics with the boot undone. I'm thinking I'll go with Plan B
