On the downside, pull-on for a tall boot means there's only so skinny they can make the shaft, or nobody would be able to get the darn thing on. Accordingly, the Tabitha measures 14.5 inches at top, 13 at midcalf, and 12 at the ankle. It's definitely slimmer than average but has a straight look rather than nipping in at the ankle -- which is appropriate for a Western style.
A note on sizing: Though a couple reviews indicated the Tabitha Tall Pull On runs a bit small, I found it comfortably roomy in size 7.5, even though I'm generally between 7.5 and 8. So I wouldn't suggest sizing up...especially since Fryes are known for loosening up after repeated wear to conform to the foot.
Calf slimness: ***/5
