I went from spinning 3x a week to once a month due to a sudden attack of achilles tendonitis.  I was having extreme pain when riding out of the saddle.  My instructor suggested I get some cycling shoes, as they are stiff on the bottom and keep your foot and ankle from working so hard while riding.  I bought this pair due to its high reviews on Amazon.  I have only used them once, but felt I needed to review them right away, because they really helped!  The pain went from an 8 on a 10-point scale to a 1 during the first ride w/ the shoes, even while riding out of the saddle.

Pros:
- easy on/off via the three velcro straps.
- very comfortable on the foot... roomy but my foot did not slip around in the shoe.
- stiff sole really helps you focus on using your hamstrings/quadriceps to pedal versus the arch of your foot or your ankle... for me, this was much easier on my poor aching achilles

Cons:
- a little tricky to install the cleats (purchased separately... they do NOT come w/ the shoes, FYI)... the little "board" into which the cleats screw in slipped around a little bit while I was trying to screw in the cleats.  Had to pull the lining out of the shoe and grab the board to reposition it.  I would probably recommend taking the shoes to a bike shop to have the cleats installed by someone who knows what he is doing.
- I had the cleats come unscrewed the first time I used the shoes.  It could be because I didn't tighten them enough... again, I would suggest having a professional install the cleats.

I would recommend these shoes to anyone looking for a basic shoe for indoor cycling.
