Review edited on 3 Oct 2013 to try and make it more helpful. I'm not sure why no one is finding this review helpful because they did not comment, so I'll just try and clarify and elaborate on what I initally wrote.

I received the same style shoe as a gift (one size too small - size 40 which is 8 American). They were adorable, so I just went one size up and when I received them they were nowhere near as cute as the picture shows. The size 41 (9 1/2 American) lose the contours shown in the picture, the larger size has more of a puffy rounded out look. Also, since the sizing on these is not standard American, they don't fit exactly right. I always wear between 8 1/2 to a 9, so the 40 is too small, and the 41 is too big. I had to buy thicker socks in order for them to fit right, but that makes my feet warmer, which is uncomfortable.

The shoes work well for spinning class. They're durable; I wear them three times a week, and they're still in great condition. They're comfortable (aside from the size issue), and the cleats (purchased separately) attached easily to the shoes.

I do recommend these shoes, especially when I hear my friends who wear the standard cycling shoes complaining of their feet going numb during class. These shoes have more of an athletic shoe feel to them (although they still have the rigid sole of a cylcing shoe) so you don't have to "get used to" them; my feet have never gone numb in them.

EDITED AGAIN TO ADD: I forgot the best part of these shoes is that you can walk around in them easily, since the cleat is recessed. You will still hear a little bit of a clink when you take a step, and they feel a little "slippery" for a millisecond when all your weight is pushing off the ball of your foot, so just be aware of that. I wouldn't recommend walking in muddy trails or using them for other athletic activities, but it's great if you don't want to take your shoes of after spin class, or you're biking outside and need to stop to run other errands.
