If your first pair of cycling shoes have seen their share of miles and are starting to beg for retirement, Louis Garneau's all-new men's Platinum Shoes would be a good place to start your search for a replacement. With a slim silhouette and trickle-down technology from Garneau's pro-level models, the Platinum is a solid step up from an entry-level or mid-range model. Garneau uses synthetic leather to shape the Platinum's contoured uppers, and instead of large mesh panels for breathability, it adds subtle slits in the synthetic leather backed by mesh to encourage airflow, maintaining the shoe's clean, sleek design. As on many of its top-tier shoes, the uppers on the Platinum are seamless, lessening the likelihood of hot spots and pressure points during long rides. Another common complaint Garneau hopes to eliminate during your rides is heel slippage, so it adds a reinforced heel cup to the Platinum to make sure you don't lose valuable watts due to a wobbling foot. The top Boa dial paired with the lower hook-and-loop strap also contribute to the cause, allowing you to fine-tune the fit along the top of your foot for the right balance of security and comfort. Anticipating that you'll be riding in a variety of temperatures, Garneau includes its Ergo Air Cool Stuff and Hot Stuff insoles with the Platinum shoes -- both are ventilated and easily interchangeable. Underneath your foot, the Ergo Air II reinforced nylon outsole will work to dutifully transfer energy from your legs to the pedals throughout your pedal stroke.
