Oliver Footwear AT 65-691 350 mm lace-up mining boot with metatarsal guard

The AT 65-691 350 mm lace-up mining boot includes the Poron XRD metatarsal guard that is comfortable, flexible and lightweight and frees the wearer of traditional rigid and bulky guards. Poron XRD creates a protective shield that absorbs up to 90% of the most intense force.

The boot comprises a hard-wearing, dual-density nitrile rubber layer outsole combined with a polyurethane midsole to ensure it is protected from shock while maintaining a hard-wearing, slip- and abrasion-resistant sole.

The sole offers resistance to temperatures of 300°C of surface contact, antistatic protection as well as resistance to mineral and organic oils and acids.

The boot features a Comfortcushion and Nanolite footbed that provides constant impact absorption, a black water-resistant upper that is fully lined with a Sympatex waterproof liner, heavy-duty Nomex heat- and flame-resistant stitching and Qflex Zero non-metallic insole to protect against penetration from nails, fasteners, glass shards or similar obstacles.

The Natureform Type 1 protective toecap with its wider shape provides foot comfort and avoids contact between the foot and the toecap. An integrated TPU Safetycell around the boot protects against scuffing and traditional early failure at these points.

The boot is available in sizes 6 to 15 and half-size increments from 7½ to 11½.

The lace-up design has also been altered to allow for the inclusion of a lace-in zipper attachment.
