For the ultimate in protective comfort and a roomier fit you?ll love choose the Brooks Women?s Ariel 18 Running Shoes. Constructed with a full-length Segmented Crash Pad that accommodates any foot landing and Progressive Diagonal Rollbars in the midsole to counteract the foots tendency to overpronate for smooth heel-to-toe transitions as you stride. The updated last makes for a more spacious forefoot while the supportive saddle and external heel counters help reinforce stability.
