It is a very good fit for my feet. I love having BOA adjustment though having 2 would be even better. I got a good price here at $135. Two complaints - the insole is extremely thin so count on retrofitting something. If you unclip by accident, the foot can slip on the pedal when trying to click back in due to the slick bottom surface of the shoe. I had read about this going in. It's not a deal breaker as you can get used to it and become more skilled at avoiding it. I do love the look of these Fizik and even wish I had gone for the edgier look of Green/Orange. My green ones are still nice.
Was looking for a different saddle from my Fabric Scoop gel which was good, but I wanted to see what the hype was about these stubby saddles. Tried a Specialized power expert which was too firm and so gave the Fizik Tempo Argo 5 a shot. It's a bit longer than the Spec saddle, allowing a little fore and aft movement, and the padding is great! Not too soft or firm and good for my 40-60 mile road rides. Only drawback is rails may be a bit short if you run a setback seatpost and need to have the rails all the way forward. Overall though, a very nice and inexpensive saddle.
I ride 2 or three times a week, about 60% on paved roads and about 40% on gravel roads and single track. This is a great value for the money. I was willing to spend more, but just didn't feel the need. The fit and finish is high quality. The sole is stiffer and gives me more power transfer to the pedals than my previous Mavic All Road shoes. I wore these for most of the summer and early fall so weather conditions were mostly hot and dry. They were breathable enough that I never thought once about overheating. I can't speak to their abilities in wet conditions yet.
In terms of sizing, I usually wear a size 10.5 or 11 shoe and the size 44 Terra fits me quite well. Snug enough in the heel and midfoot with enough room in the toe. The heel cup is a bit padded for comfort but also locks your heel into place. My foot is a bit narrow and I think these work well.
The single Boa dial effectively locks the heel in place and it's easy to use. Compared to traditional lace systems, I like that I can reach down and adjust the tightness if I feel it is needed. The tongue is a nice slick material that allows it to slide freely as you tighten the Boa so one-handed adjustments are easy enough. One small complaint is that I do sometimes feel a slight pressure point at the top of the tongue. That might be due to my personal anatomy. The strap on the forefoot is essentially useless because even if you ream on it, it doesn't tighten the forefoot. That's fine since I don't need any additional snugness there.
The cleats gave me all the traction I needed for climbing steep trails off the bike. They arenï¿½t as easy or comfortable to walk in as my Mavic shoes, but thatï¿½s partly due to the stiffer sole which is better for actually pedaling. A fair trade-off in my opinion.
The stock insole is quite thin and I would recommend after market soles. I do feel a pressure point under my big toe which may be from one of the cleats. A proper sole should mask such pressure points. I canï¿½t judge the Terraï¿½s too harshly in this regard because pretty much all cycling shoes come with poor insoles.
I had been seeking this shoe for some time and saw a great offer on WesternBikeWorks site. The shoe is very pleasing to looking at. While the velcro straps might be 'old school' technology, they do a very efficient job of keeping my feet in place with as much wiggle room as I might need. I will say though... I guess my feet are slightly wider then the sole of this shoe. The first couple of ride I ride sense that maybe I had tightened the velcro straps too much, but the discomfort truly at the bottom of my feet. I know that some of Fiizik's other shoe models have been updated for 'wide' feet, but not this R5 Powerstrap. Since the break-in period, the shoes have seemed to have formed a better fit. These shoes aren't maybe 'as comfortable' as my time-tested SIDI's. Also, the soles of these R5's definitely don't have the stiffness of a 100% carbon sole. I'm not a big cycling tech guy, but the difference in feel of power in my strokes from these shoes vs SIDI is a tad less reactive. Would I buy again? At the price I paid... yes.
