NWOT - no box. Color: Blue Coral / Evening Primrose The HOKA ONE ONE CHALLENGER ATR 6 is back for a sixth iteration. This men's trail shoe once again confirms its reputation as a versatile model. Agile and fast on the trail, this shoe has a midsole that incorporates a geometry that ensures a fluid crowd on the asphalt. The outsole, with its studs, reminds us that it has its origins in trail running. The lugs are moved closer to the heel for a smoother, more fluid ride and are spread over a larger area in the midsole for better traction on trails and in bad weather. This 6th version also includes midfoot overlays for improved support and a counter for excellent stability. This is a high performance shoe with a good reason to be noticed for its trendy look.
