These just did not fit, too small, my toes hurt after a few hours. So, to be sure they fit, I would measure your foot with MM.
Hold the pencil straight up and down and in order to fit these properly, but tight and snug like most of us like, you should be around 272mm-274mm, they are fully heat moldable and can probably vary that measurement slightly. To give you an idea, i measure about 278-280 and they hurt after a few hours. Not bad, but enough that i did not want to keep them. I bought a set of 41.5 and happy now. They are fully intact, NO cracks in the carbon fiber, no holes in the boots, some scuffs to be expected, they are strong and skating on them, very sturdy and super stiff boots that are really comfortable as well.
The straight away strokes are VERY powerful.... The 3 Point frame is an amazing system yet, if you short track, you may want to remove the middle boot mount bolt so the frame can flex i little. I did not do this, it seemed just fine to me. They do have a super high spin Fafnir bearing, i replaced bont bearings.
They spin for about 1 min. Heed my suggestions on the measurement. They are not the same as older bont 41, they are about 5mm shorter then the old 41 models.
