The Georgia Boot Men's 11 in. Wedge Pull-On Farm & Ranch Wellington Work Boots bring the comfort of all day wear with a tough, durable construction. The SPR™ leather resists caustic chemicals and barnyard acids. It has 3 times the strength and it is able to resist abrasions 2 1/2 times better than traditional leathers because of the way it has been tanned. These men's work boots have Goodyear® welt construction. By building these pull on work boots this way, it gives them durability and strength; plus it allows you to have the outsole replaced once it has worn down. Pull loops at the top of the pull-on boots help you get into them each day. Inside is a soft lining and a cushion insole, both of help make these men's pull on work boots.
