The Shimano RX600 Wide is a race-oriented gravel shoe that strikes just the right balance between comfort and performance. The carbon-reinforced composite sole offers all-day pedaling performance without sacrificing walkability off the bike. TPU lugs on the heel and toe offer grip when hike-a-bike situations become necessary. BOA dials allow us to dial in our perfect fit while the Surround Upper hugs our foot securely. The wide fit offers a higher internal shoe volume to fit a wider range of riders.
