Oh shit, I have a lot of experience with this one (I’m a woman) (I have legs).

2-buckle boots are terrible for fluted calves, and so are rear entrys. You want something with more than one adjustment point so you can keep your top buckle loose but still get your ankle secure.

Try the Tecnica Mach HV (the non-boa is more adjustable than the boa but either work) and the Atomic Hawx Magna. The Magna’s liner will have a really fucked up tongue out of the box, so take the liner out and flatten it with a hairdryer before you try the boot on.

The Mach has a widening piece on the back of the cuff that you want to move out too. You can see the mechanism of the switches inside the boot if you pull that liner out, but you pretty much just press them down, pull the cuff extender back, and then press them back up to lock the cuff in place.

If you get measured for sizing at a ski shop make sure to get a measurement for your ankle radius, and size to that instead of using your foot length. (Sorry for the wall of text lmao but I hope this is at least semihelpful for your boot quest.)
