huh? just my silly name for sock sliding around on the wood floors
You can pick up a real one cheap!!! Look on Craigslist and possibly in the free section. Or I could find one for you up here.
Sock sliding doesn't come close to a Nordic Trak workout. No upper body! The Nordic Trak can vary the (1) slope of the track so you're going 'uphill', (2) the foot slides by varying the tension on the belt that wraps the wheel they drive, and (3) the arm pulls by twisting the friction drive that the arm cords rotate.
It is a simple, long-lasting machine that requires no power to operate, other than your own.
Gee...$23! Good buy!
As far as finding room for it, remember it is very narrow. So maybe a hallway? Beside the bathtub? I think the Nordic Trak has a classic "sculptural" look, at least to us XC skiers. So I wouldn't mind having it near a wall in my bedroom or living room.
I maintain it by waxing the wooden slides. Surprisingly I've never replaced any of the cords or belts; they seem to last forever. Adjusting the slide belt tension is easy, after you get the hang of it. Good luck.
