As the name suggests, the Giro Prolight SLX II road shoes don’t weigh much, hitting our scales at just 235g for a size 45. You may have seen lighter weights reported on other shoes, but this is often for the smallest size. Trust me, these are ridiculously light.

In order to save weight the Giro Prolight SLX II road shoes do away with ratchets and dials, instead opting for three simple straps that offer plenty of adjustment and a secure fit. The design also includes titanium hardware on the cleat bolt holes and straps.
