I waited to put 165 miles on these to break them in before offering my two cents. I really appreciate the narrow footbed and the stiffness of this shoe. The Li2 BOA dials are a breeze to operate and easy to adjust during a ride. The inside heel-portion has an interesting anti-slip design that helps to secure the back of the foot inside the shoe. On the sole there is a port to allow ventilation at the front of the shoe. I am really happy with these shoes, and I can be very hard to please. They have been easy to clean after each ride: I use bleach-free Clorox Scentiva wipes which are stated to be safe for vinyl surfaces, and the wipes keep my white shoes looking great.
Can't give a full in depth review because they will be a Christmas present. I have been searching for a pair of white cycling shoes for a while. Tried a few and these seem to be what I've been wanting. I tried them on for a few minutes and felt great and just the look I have been wanting.
I bought these a couple weeks ago to replace some Giro Empire lace ups. The Tempo Decos is billed as a 2nd tier road shoe, maybe due to the single boa dial. It has a great stiff sole and the single boa tightens things nicely. I have a few hundred miles in them and they needed very little break in (just the tongue was a little stiff, took 1 ride). If you like your cleats farther back like I do, this is more adjustable than most other shoes with a moveable cleat base. Nice and light, very comfortable and they have a bit of sole ventilation also. I am a 44 in sidi and giro, followed the chart and fit a 43 in Fizik. Highly recommend.
