Review on Thinvik 6 Degree Float Road Bike Cleats for Shimano SPD-SL Locking Cycling Pedals, Compatible with Shimano SH11 System Shoes by Darren Anderson

So far they have held up well as they are a bit heavier for the driver. The official ones are around 15-20% heavier compared to the weight of the boot and they're a little harder to carve than the official ones, probably around 20-30% harder compared to fresh boots. The higher clipping difficulty might confuse you a little if you're used to easier clipping (potential security issue). Some other differences are that the bottom two slots are narrower than the official lugs, so with them you also have less room for horizontal adjustment (about 2mm less, horizontal adjustment with the included plates at 0.5-1mm) . less if you have official cleat plates with rounded edges.o.).
