Shimano R171 review, CyclingTips, February 2015 (see here):
"Shimano is best known for its groupsets and wheels but you'd be mistaken to think of the company's extensive line of soft-goods as an after-thought. With the success of Shimano's R320 road shoe, the company has given its flagship shoes a facelift and has launched a new top-end model, the R321, along with a more affordable option: the R171, which supersedes their mid-range R170.
....At first glance you'd have a difficult time telling the R321s and R171s apart aside from their colour. Both shoes use the new â€˜Surround' upper design which is made from Teijin Avail 100 ultralight fabric. This new design is meant to provide more support and uniformity for the instep of the foot with the wrap-around fit.
The two front velcro straps with a ratchet buckle is a proven formula for Shimano's shoes. The straps pulls the upper down on to your foot and the ratchet pulls your foot up so that everything fits snug. The whole system pulls the foot down as close to the pedal as possible.
The differences between the shoes are subtle and you need to look closely at the lower half of the shoe to notice what sets them apart.
The R321s have vents at the toe cap and on the top of toe, and the R171s do not. Also, the 321s use a more textured and more durable fabric at the heel as opposed to the R171s.
The R321s have Shimano's maximum carbon sole stiffness (their rating of 12) while the R171s are rated at a 10. That's not to say that the R321s sole is something without any give. I've worn shoes that are too stiff before, and these are not too stiff.
The differences between the soles of the shoes is something that's very difficult to notice if I'm honest. However the R171's simpler insole and slightly more pliable construction has lead to a tiny weight advantage â€" the R171 shoes weigh 486g per pair (size 40 EU) compared to the R321 which weighs 489g.
If you don't have the need or desire for custom fit shoes, then you'll be thrilled with Shimano's new R171. It feels like a top-end shoe without the price premium and until you look closely you won't be able to see the difference between it and Shimano's top-end R321. It has the same features, fit and technology minus the Custom Fit."
Shimano R171 review, BikeRadar, August 2015 (see here):
"The R171 shoes are extremely similar in looks to the Japanese brand's top-end R321 offerings, and sit under these in Shimano's price scale â€" Ultegra to the R321's Dura-Ace. Despite being half the price of the pro-level shoes, the R171 gets just about all the same features except for custom moulding.
The Surround perforated upper is made from ultra-light Teijin Avail 100 synthetic material, which is designed to improve fit and increase support under power. The white section wraps from the outside of the foot almost to the inside arch, incorporating a padded tongue. The black section then covers this and is secured via two Velcro straps and one ratchet, which has two mounting points via a 2.5mm hex bolt for a more custom fit. It's a pretty smooth setup that looks a bit like you're wearing half an aero shoe cover.
The full carbon sole incorporates Shimano's Dynalast technology and is designed to be very stiff but with a bit of toe spring, which the company says offers smoother, more efficient pedalling with less energy loss. The shoes retain the longer fore-aft cleat adjustment slots of the R170s, which give around 1cm of extra movement beyond what your cleats offer.
There are also heel and toe bumpers to avoid damage to the carbon when walking. The heel protector is a chunky number that seems to have done its bit in protecting the sole, with only a few small scuffs and scratches in about 300 miles of riding despite this tester's gravel driveway.
The insole is made from dual density foam and is shaped to help cup the heel, which is also supported by a fairly stiff, padded heel cup.
Ventilation-wise, there are hundreds of perforations on the upper along with a mesh vent over the top of the toebox. There's also one vent on the sole under the toes. The R171s aren't quite as cool as shoes with more mesh, such as Pearl Izumi's Elite RD IVs, but there was certainly no overheating in warm, sunny conditions.
Out on the bike, it's clear what a stiff base this is, with no noticeable flex whether sprinting or grinding up climbs. The Surround upper really adds to this feeling, keeping you totally locked in but without discomfort.
There's never the sense that you're just pulling against the straps â€" feet feel planted to the insole and securely hugged, perfecting the interface between foot and pedal. The ratchet strap doesn't seem to have quite as many engagement clicks as a dial, and depending on sock thickness, a little more control would've been nice. It's probably not something you'll dwell on while riding, but the competition is starting to pull away from Shimano in this department.
It's worth noting that the R171s seemed to come up a little larger than other older Shimano shoes I've used. At 296g per shoe (592g for the pair) in size 45, they're certainly on a par with other shoes in this price bracket.
Overall, Shimano's R171s are top performing road shoes that are undoubtedly stiff, and comfortable enough to render the lack of custom shaping irrelevant. The ratchet strap might not be the ultimate closure system, but it's not dead yet."
The R171s remain some of the best road shoes at this price point â€" but competition's getting fiercer

Shimano R171 review, RoadCyclingUK, April 2016 (see here for full review):
"Look back at the final sprint at Paris-Roubaix and you'll notice two of the top three riders were wearing Shimano's distinctive R321 shoes. They have a divisive design (in every sense of the word), being half black and half white, and a high price â€" £249.99. However, for us mere mortals Shimano have their second tier shoes, the R171s, at £129.99.
There's a lot to like about Shimano's R171 shoes, which offer plenty in the performance stakes for the £130 price tag, and share many of the features and the styling of the top-end R321 footwear. The sole is stiff when putting the power down but Shimano haven't neglected comfort, either. Perhaps the ratchet and strap system is a bit of a throwback and lacks a little adjustability but it still works well. It'd also be nice to have replaceable sole buffers but that shouldn't take away from a pair of strong performing shoes."
