I can understand your frustration, I purchased an inexpensive zip boot from Sportsmen's Guide for warm weather wear. They are cordura/leather with rubber bottoms and scent free. I guess they are scent free because when they arrived and I opened the box it was like walking in to a tire store. I sprayed them with everything I could think of to no avail. Finally I wore them to the the field for scouting only and shed hunting and they finally lost the smell almost a year later.
