SERVUS CT Knee Boot features Comfort Technology (CT), allowing the boot to conform to the shape of the foot, especially across the instep and around the heel. Scalloped top rises higher in the front than the back. Scalloped top line helps reduce irritation at the back of the leg. Available in graduated heights so that the height of the boot will be appropriate to the size of the foot. Foot Form insole provides added support and comfort underfoot. Indoor/outdoor outsole design, the Trac10, provides a stable base for walking and standing. Seamless, waterproof, injection-molded PVC boot is available in steel-toe and plain-toe models and men’s whole sizes 3 to 15. Norcross Safety Products, Rock Island, IL
