Running the first few steps in the Cloudrunenrs felt a little strange and can even be slightly awkward as instead of reverting to your normal running style the shoes encourage you to run more on your mid-foot. After a few minutes of running you soon get into your stride and then the shoes really show off their features. The faster you run the more you feel like the shoes are propelling you forward and although not as smooth as the natural running shoes that I have run in, you can really feel the lugs working to catch your foot on landing and then propel you forward during toe-off.
I am used to running in shoes with a 4mm heel to toe offset and so moving to the 8mm Cloudrunner offset wasn’t a problem for me and I felt no lower leg discomfort at all either during or after running in the shoes. I cannot speak for people that are looking to make the move from conventional to natural running shoes, but the 8mm heel of the ON is a relatively small jump and I don’t expect you to feel much discomfort after your first run or two. Having said that, it is prudent to break-in any new shoe and so I would suggest taking the ON’s out for a shorter run before you start training in them for long distances.
