My field boots are pull on.
No zipper or elastic gullet in them.
I do have laces at the ankle to tighten to make the boot fit my ankle better.
Dress boots have no laces and not supposed to have zipper calves either technically...they too pull on.
You learn how to wiggle in and pull off by yourself if resourceful or use another's butt as the push point and their arms as the yank-off if you forgot your boot jack....
Paddock boots if not lace-ups or zipper had thick elastic inserts on the boot sides that held you tightly held tightly.
Think more the look and definition of jodphur boots..
I had a pair as a adult...comfortable beyond belief. What can bind on lace-ups is not there...
I wore them to death and after resoling them 3x my cobbler told me he had no more leather strip left to stitch to...they was done for.
Only other boot that came close to that comfort was a pair of zip-up the front paddock boots think advertised for the "pro-rider" ???
Heavy duty zipper so strong I had to use a hoofpick to pull the zipper up or down the first month I had them even after candle-waxing the zipper for slip-ease.
Again, I wore them in the barns working doing barn chores till I killed them too...
Only reason why I even had those was my friends owned a tack shop and these were demos that did not sell so they gave them to me for peanuts compared to what they were worth...manufacturer salesman did not want them back so they became mine for think $20...no way was I walking away from that deal.
I don't buy unless comfortable cause I did not have time for blisters or hurting feet...all my clothing is like that. Comfortable when put on or not purchasing, period.
Today I don't buy because I'm not spending that kind of money...ridiculous when they wear out just as fast if not faster than Ariats which are 1/2 the cost...yes, I'm frugal aka cheap!
Today like many others I ride, do barn chores and yard-work in my Ariat Terrains that give me ankle stability and foot protection but are friendly to walk around in and safe astride with the heel to not slip through a stirrup easily.
