Bonanza Boots® ProSeries line of work boots are manufactured with PU Direct Injection Technology. This type of construction provides superior comfort and stability; all while delivering a strong lightweight outsole. The sole is built without glue or stitching, which provides a watertight seal, flexibility and stability. Below are a couple of reasons why our ProSeries line work with your feet, not against them.

Rubber Outsole

Our PU/Rubber dual-density combination fuses great shock absorption with flexible freedom of movement. This rubber sole skid is oil, slip and acid resistant; you can always count on it to be light, flexible and durable.

Glove-like Fit

Glove-like fit combines custom comfort with smooth, even closure. A padded tongue and collar along with a cushioned footbed surround your foot in comfort.

Removable Latex Insole

Ultra smooth memory foam, shielded with mesh lining for even more comfort. Its breathable and anti-moisture performance allow a better air circulation inside the boot, helping feet stay dry.

Polyurethane (PU)

An adaptable material that supports the foot with supple flexibility and variable hardness depending on the application. The PU material is directly injected to the upper and rubber sole skid, which makes outsole separation from upper nearly impossible.
