Alantco makes Tru-Spec. They are right around the corner. Talk with them.
I found out a long time ago that if I alternate between two pairs of boots, it allows the boots to dry out between uses, and the salt doesn't build up on the seams like that. You might want to put your boots in front of the refrigerator at night. The motor will help dry them out. Lay them on the side with the opening facing the frig. Also, if you wear cotton socks, ditch them for wool (I'm serious, year round.) It will help keep your feet in better shape, and keep the boots dryer.
Your feet deserve better than Tru-spec. Buy something at least twice the cost/quality.
Yes, buy better boots. Those terrible.
I work for Atlanco, we do not service end users. The CSRs will just send you to the dealer.
