Made to fit the shape of a woman's foot, these ultralight work boots incorporate innovations in environmentally friendly and sustainable materials while maintaining absolute durability, comfort and performance. 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 ReGripDLT, with Vibram® LiteBase outsole delivers best-in-class slip resistance. The BOA® Single-Dial PerformFit™ Wrap delivers a micro-adjustable, precision fit, delivering improved heel-hold, energy efficiency, stability, and control.
