MBR Mountain Bike Rider: FLR F-75 PRO SHOES. The F-75 Pro from FLR looks tough and aggressive, almost like a piece of military hardware…. As a mid-priced race show the F-75 is spot-on – it’s rigid, a reasonable weight and has a good tread design, which is aggressive but shallow enough to run comfortable. There’s also plenty of space around the cleat area to engage a range of pedals easily, even in the mud. All in all, a distinctive and well-considered shoe.
