Materials made from renewable resources and post-consumer recycled plastic are used throughout — everywhere from the outsole, midsole and bootie to the footbed and even the laces. ASTM-approved electrical hazard and aluminum safety toe protection combine with Red Wing waterproofing to make Apex boots ideal for work in construction, transportation, warehousing and other medium-duty trades, indoors and outdoors. Underneath, the Vibram® Eco outsole delivers best-in-class slip resistance. The single-dial BOA® PerformFit™ Wrap delivers a micro-adjustable, precision fit that locks in the heel to deliver improved energy efficiency, stability, and control. BOA® is engineered and guaranteed to perform in the toughest conditions.
