(Boxe I train in Thai) Extremely comfortable during training, They are light but They offer a good protection for the shins. For the kind of model (sock-like) a bit difficult to take off from the sweaty shin after the workout but nothing major. I used to have a pair of thai boxing shin protectors from Paffen sport before, the Fairtex ones are qualitatively far better and much more comfortable. One advice, Especially for the beginners: better to spend a bit more to buy equipment than a bit less. I tried to save some money by buying the Paffen Sport "cheap ones" and found myself in need of a new pair after 2 months. I have been using the Fairtex ones for 2 weeks now and my calf Although is a bit fat and so short, size M fits very comfortably and the material is quietly perfect like the first day. Buy them! :)
