Hi T.C.,
thanks for your comments and concerns. Most people unless they are pigeon toed stand duck footed with their feet facing slightly outward which is the same position your feet face when using wheelskates so that the outside part of the front of your foot is over where the wheel contacts the ground, which takes a bit of getting used to if you are used to using inline skates which have a different wheel alignment.

I am 50 years old, I have a weak left knee due to ice-skating and snow-skiing accidents when I was much younger and I have never experienced any knee or joint problems in all the time I have been using them and I’m on them for a couple of hours at a time around once a week or more; recently I did 15 hours in 3 days and have previously done a lot more than that in a few days and I have never had any knee or joint injuries; and in the early days I was on some very crude prototypes compared to what we have now. People who are new to them feel extra muscle tension because they are nervous and not relaxed like when someone first tries ice-skating or snow-skiing.

One of the advantages that Wheelskates have over other forms of skates is that they provide support the whole length of your lower leg so there is not chance of ankle injury. I have fallen many times and so far I have not had any knee injuries either and I’m not sure if that is because your knee is extremely unlikely to hit the ground or because I have just been fortunate. Another advantage is that the large wheel comes into contact under the ball or your foot which is what we use for forward support and where we instinctively pivot when turning and this combined with the large wheel has other dynamic advantages which I don’t have time to go into here.

It has taken me a while to respond to your comment because I spend most of my time in China where they censor sights like YouTube, Face Book & Twitter so they can’t be accessed in China (except through a VPN) and sometime last year they took Vimeo off and have only just allowed it back.
