There's leather, and then there's SPR. If you're a farmer, do yourself a favor and wear boots made with SPR leather. The leather undergoes a special tanning process to make it three times stronger and two and a half times more abrasion-resistant that conventional leathers. This offers better protection against barnyard chemicals. SPR leather resists caustic alkali, sulfuric acid, calcium hydroxide , potassium phosphates, caustic potash and other barnyard acids. It's also pasture-proff.
The Durango Men's Tan SPR Leather Farm & Ranch Boot has a covered cushion odor eater insole and a leather foot and shaft. The Carbo-Tec Mini-lug outsole is oil and fuel resistant.
