Just came back from my first Ski Walk and absolutely love it!!!  As an aerobics instructor, I can highly recommend this exercise to everyone and anyone.  I will be talking these up to my students who need to get on dry land for cross training even on our indoor track.  I am amazed at the core and arm work and posture alignment while walking with these.
Thanks for the FAST shipment and great customer service!!!  also, your DVD and written cues for using the equipment are perfect.
