These stove pipe top boots are more than likely made in the late 50's/early 60's and I'm guessing they were custom made. There are no stamps, maker's mark or size, but they very much resemble M. L. Leddy's boots of this era.
They're in excellent condition for their age. No cracking, leather is soft with good soles.
We're guessing that they are a ladies size 6. They measure 10.5 from the back of the heel to the tip of the toe. 3.5" across the widest part of the foot. They have 12" tops and 1.5" heel. The diameter of the top of the boots is 11.5"
