The Propet® Spero Boots combine a practical design with lightweight comfort for everyday wear. Embedded puncture-resistant footbed plus removable open-cell insole that moves moisture from the foot for a cooler, healthier footbed. Shock-absorbing midsole with lightweight Ethylene-Vinyl Acetate (EVA) foam provides superior cushioning. Specially designed slip-resistant-rated rubber outsole provides additional traction and stability on wet/dry surfaces, meeting ASTM F3445-21 requirements.
