In 1957 we introduced the Grange. A non-insulated, do-it-all rubber boot that our customers knew they could always trust. Six years later, an insulated version of the Grange came to be - the Burly. Today, these boots are alive and well. They&';re still made from our proven ZXT Rubber. They&';re still built to perform under the harshest of conditions. And they&';re still the boots you can call on to get the job done. Extended sizing available for women. 100% Waterproof Protection Rubber is naturally waterproof and with our proven formulas, our rubber remains durable and waterproof year after year. Adjustable Top Strap Customizable for a secure fit around your calf. Ankle Fit Our revolutionary fit ensures a secure and comfortable fit around your ankles, while gripping the top of your foot and locking your heel in place.
