The unique 4-wheel drive type action of Nordic Ski Walking makes beach walking and running a blast! Even men that walk like apes start walking automatically with a super straight back when utilizing the perfect length poles. One-piece poles custom fit to each individual’s height are safer, lighter and more durable than cheap twist-locking adjustable/telescoping/collapsible poles. Quality poles available from WWW.SKIWALKING.COM and the American Nordic Walking System.
