These shoes literally learn the shape of your feet with every next ride. The first feeling is like a wooden block around your toes, but after one month of training in them, you will be amazed by the comfort and power transfer. I'll definitely buy one more pair! P.S. If You are a triathlete, keep in mind that Your feet may swell after running sessions. I recommend measuring your size during the "on-season", while your training volume is high.
