For those of us who prefer flats when we are shredding the trails, our world of technical mountain bike shoes just got a bit brighter. Fox Racing finally brought the BOA closure system to their flat pedal shoe lineup, giving us the Union Boa Flat Mountain Biking Shoe. This shoe features a one-piece molded TPU upper with mesh cutouts for breathability and durability. The Dual BOA Li2 closure system provides a super quick and secure closure system, and the high and low arch support gives us a support and comfortable fit. A molded toe cap wards off rock strikes, and the EVA midsole cushions our feet and absorbs impacts.
