Swapped my Prophets for these and they're simply perfect. Much better feel, fit and stiffness than the Prophet. I have a pretty standard foot, US 9.5 and the 27 fits perfectly. Had a 27.5 in Garmont and my toes got major pressure in the tow box. Tried, the 28, but they were too big. My weight is 165, I use the TX Pros with blue springs set to 3 and it's the perfect match to drive my Dynastar 6th Sense Slicers. Cheers.
