Keen Men's Seek Trainers Grenadine Ocean Depths This is a conceptual process about japan s mysterious killer ninja hang. Keen have applied their off road footwear knowhow to a technical trail running shoe. The result is the Seek, a lightweight, stable shoe which combines considered details like that ultra springy QuantumFoamX cushioned sole with Keen's spacious Original Fit toe box. Chunky 4mm multi directional lugs keep things grippy, while those abrasion resistant uppers are reassuringly tough without tipping the scales. Classic Keen comfort, built for speed.
