Review by me from here
These are wonderful cycling shoes approximate 500 miles in them. Wider toe box than my Sidi's and Mavic's which I find more comfortable. I feel more pedaling efficiency (as proclaimed) with these shoes than previously mentioned shoes. The lining is very plush adding to the comfort. The adjustable placement for the ratchet buckle across the top of your foot really helps dial them in, so make sure you try both settings. It was tough not buying the 321's since I paid more my Sidi's but I wouldn't have been able to take advantage of the moldable insole, so the 171's made more sense and are working out great.
