Great Shoe!
These are my first venture into Tri specific shoes and i am totally happy with the purchase. I have a little over 100 miles on them so far. The first couple of rides were strange because I am not used to such stiff soles that transmit every bump right to your feet. But every ride the shoes get more and more comfortable. I bought these a bit big because my last shoes were a bit small and I did not want to deal with that again. I wear a size 13 shoe, and ended up getting a 47 (a 14 by specialized standards) because my left foot is slightly larger and was knocking against the front. The velcro strap does a good job of staying tight (not as good as a ratchet device, though). I put these shoes and and instantly i feel faster. I think this is a great shoe for anybody looking to upgrade, especially for a carbon soled shoe (the Sidi is more expensive and you don't get the carbon sole)
Great warm weather shoe
I got these as a Christmas present this year. I figured that if I was going to do Ironman this year, I needed a proper pair of shoes (and not a pair of mountain bike shoes). Read up on all the possibilities out there and these really caught my attention - great reviews, great write ups, and same brand as my mountain bike shoes, which I love. So I tried them on and they were great. the stiff carbon sole has made my pedal stroke much more efficient and the vents are great on warm days. However, being in Canada, cold weather riding isn't ideal in these shoes...your feeit will freeze! The double strap entry and the little tab on the main strap to hold it in place when they are waiting for your feet is pretty cool. They are extremely comfortable and I would recommend them to anyone, pros and newbies alike.
Specialized Trivents
These shoes really rock!!! They keep my feet so dry and cool that I don't even have to wash my socks after I ride...just kidding. But seriously these shoes are well priced for a durable carbon soled shoe. While there are two straps, only the top needs to be used, the bottom strap can be adjusted and left in place. The top strap has a notch in it that holds the strap open and keeps it out of the way so you can slide right in them without using additional velcro or rubber bands. I have had absolutely no problems with these shoes.
Specialized Trivent Triathlon Shoe
This is a great shoe. As far as I can see it is the cheapest carbon soled tri shoe on the market. Awesome price. I broke the first rule of triathlon and tried these shoes in a race. Rule broken - never try new untested equipment in a race. The shoe gave me no problems, the race was a 1/2 iron. I wore the shoe without socks and no blisters. What I love about these shoes is how air flows through cooling your feet. This also enable you to wash sand from your feet whilst on the bike.
The carbon sole offers an amazing peddling platform, compared to normal shoes it is so much stiffer. However, the carbon soles transfer more stress to your knees and I could feel this for the first couple of rides


Best I've tried
This shoe is the best top of the line shoe that I've tried. I've tried the Sidi T2, LG Tri Air 2, Pearl Izumi Tri Fly, and the LG Carbon Tri-Air. By far this was the best. Great sock-less comfort and as much ventilation as you would get if you rode barefoot. I chose these because I wanted a high end shoe to use in the Ironman Arizona. I was very picky about fit, comfort, function and style, and these came out on top by a mile. As long as your not getting these for winter riding your going to love them. I chose the silver color with no regrets.
