Kaha 3 sizing issues?

Anyone have sizing issues with kaha 3s? Never had an issue with hokas before now.

I’m a size 11 with most shoes, including bondis and speedgoats.

Im going on a 9 day trip that will involve a lot of hiking and I’m not sure which size Kaha 3s to go with. It feels like I’m in between 11 and 11 1/2.

The 11 1/2s are creasing with every step and feel awkwardly big. But the 11s don’t have a lot of room in the toe box and I’m pretty sure I’ll get blisters, especially with a lot of downhill impacts.

Am I overthinking this or just out of luck with these boots?

11s are on the right and 11 1/2s are on the left
