Simms' new Intruder® Felt blazes trail and wet-wades through four seasons with stamina and finesse. Integrated neoprene socks block debris. Dual-density EVA midsoles mitigate shock, while ESS plates keep cleats in check and enhance balance and control. Advanced features include nonslip Vibram® Megagrip rubber outsoles with integrated felt pads for superior grip. Abrasion-fighting welded TPU pads are seated in strategic zones, and a full neoprene lining combines wading comfort with convenient on/off capabilities.
