Here at O’Neal we have sold over 2 million MX boots since we began, way back in 1970. This vast experience in developing market-leading boots means the Sierra (entry-level) and Sierra Pro (advanced) now introduce this knowledge and expertise to the Adventure market.


As with all of our boots, these new products are designed, developed and engineered by our team of boot specialists from the Montebelluna area in Italy, home to leading boot brands in both the motorcycle and outdoor sports worlds. The result is a perfect and market-leading fit for these boots.


We use the same tough Microfiber material as we use for the MX boots, the same outsole material, the same ankle protection and the same buckles. High feature level technical product was a great price. We added a waterproof and breathable PU membrane for protection against the elements.
