BikeRadar : FLR F-55.II shoes review. No-nonsense XC-geared footwear. Impressively stiff race-focused shoes for the money. The first thing you’ll notice is the stiffness of the reinforced nylon sole, which uses a raised inside lip to create a semi bathtub design for minimum flex. In fact, it isn’t far off lower priced carbon shoes in terms of pushing your power through to the pedals, so racers and speed freaks on a budget are going to really love them. If you’re racing cyclocross or front-fanging up steep, slippery slopes for any other reason, being able to screw toe studs in will be a bonus too.
