SPENCO Heavy Duty- X Train innersoles

Uniquely designed for unforgiving surfaces, Spenco Heavy-Duty Insoles combine special "forefoot" and "heel strike" cushions in addition to the basic PolySorb insole to provide maximum support and comfort for people on their feet all day, like hikers. They are a good replacement for the popular Hiker insoles. They are great for workers seeking all-day comfort, cushioning and support or who want targeted shock absorption to soften heel impact. They are recommended for increased shock absorption and heel strike protection, reduced friction to help prevent blisters and increased energy return for improved performance. They are made from Rubatex neoprene injected with nitrogen bubbles and covered with multi-stretch nylon. A contoured layer of lightweight polyurethane is bonded to the neoprene to help cradle the heel and support the arch. This unique cushioning system is the best combination of shock absorption and energy return. They are unconditionally guaranteed for one full year.
