I have actually tried skinning on a Woodway 4 Front. It’s doable but you can’t really get a good forward glide on the skins. I have not tried it without skins, because I was to afraid of damaging the belt with the edges. I have even used wider skins than those fitting the skis. Besides the skins get a black from wearing off the belt so I stopped doing it. But the main reason is still the lack of forward glide. The width and length are fine once you get used to planting the poles (with walking rubber covers attached) close to the boots so you don’t hit the treadmill off to the side of the belt.
