The Springfield boot is designed for comfort without compromising protection. Engineered to conform to the natural shape of the foot, Ergo-Fit technology ensures the best possible fit. The composite safety toe cap and composite midsole ensure the Springfield boot's weight is kept to a minimum, without sacrificing necessary protection. The addition of the Pro-Comfort insole continues the lightweight theme, but also provides arch support and a layer of 3D memory foam for even greater comfort. As if that weren't enough, the Springfield is also waterproof and includes a Hydroguard liner, which allows the foot to breathe without allowing water to pass through the lining.
