Shimano's midrange shoe lacks the already broken-in feel of the $360 custom-fit SH-R310, but it's just five grams heavier per pair. And the R190's snug heel cup and comfortable upper make the most of your output. The forefoot offers wiggle room, and those with narrow feet will appreciate the micro-adjustable buckle's optional mounting point, which places the strap in the middle of its range. The R190's carbon and glass-fiber sole feels just slightly softer than the unidirectional all-carbon sole of Shimano's pricier offerings.--Ron Koch Buy It: If you want a medium fit and Shimano's legendary durability Forget It: If your feet require special tweaks for a comfortable fit(www.bicycling.com)
