Needed a CSA, waterproof, composite hard toe, black leathert, with a zipper and for wide feet. This boot, although expensive tick all boxes. The only thing with this boots are they are s little hard to put on, even with the zipper. I didn't test those boots on rain yet. I like them and recommand them.
Easy and fast order model 5751 having a zipper on the side and seem to be a good product.
