Have had these since the spring and only ran in them three times. I found a pair that just worked better for me. Great comfortable shoe, fits wide and feels like a sock when you put it on. These shoes are in like new condition. From the website: Fits like a track spike but performs like a trail shoe. Low-profile, lightweight, 4mm drop trail runner on neutral platform. Trail-specific soles have sticky rubber centres and lugs with sharp edges for great traction in all conditions. Uppers use single-layer mesh throughout for ventilation strategically placed overlays provide targeted support where you need it. A mesh inner sleeve wraps the foot for a plush, comfortable fit. Midsole have moulded sockliners to enhance support underfoot. Compression molded Phylon foam delivers great forefoot snap and a responsive ride. Outsole have a rugged Waffle tread for multi-surface traction, sticky rubber centers offer excellent wet surface traction. Rubber forefoot is sticky for traction on wet surfaces. Aggressive, sharp lugs for optimal grip and quick and easy mud shedding. Heel is rounded to roll with the ground, promoting a natural range of motion.
