Wolverine DuraShocks comfort technology makes its name as "The world's most comfortable boots. Guaranteed." How? DuraShocks lightweight dual-density construction weighs 1/3 as much as rubber, yet absorbs 4x's the force. Compression pads in the heel and forefoot compress and dissipate forces before they reach the feet and legs. And a closed-cell PU footbed retains its spring for an extended life cycle. Quality Goodyear welt construction. The Ignham 12" pull-on wellington work boot features a distressed full grain leather upper. Unlined. Soft toe.
