More and more walkers are discovering the benefits of using one or two walking poles. Poles can provide valuable support when walking on uneven ground and can significantly reduce jarring on knees and ankles when walking downhill.
There are several different styles of handles, so you can find a comfortable grip. Look for a stick with a spring mechanism built into it, which will reduce jarring on wrists and elbows.
Your new poles will no doubt travel in your suitcase so make sure it collapses small enough to fit.
Everyone can benefit from the use of walking poles, for walking further, exercising / strengthening upper body, for reducing knee jarring going downhill.
