Fizik Ergolace 2 GTX Flat Shoe All-weather adventure, anywhere The Fizik Ergolace 2 GTX Flat is a waterproof flat pedal shoe built for riders who refuse to let the weather dictate where they ride. It carries the same updated wider fit and reduced-bulk construction as the Ergolace 2, now with a lightweight GORE-TEX Invisible Fit membrane that delivers waterproof, breathable protection without adding weight or bulk. A low-profile ripstop upper dries quickly when conditions change, and the reinforced toebox handles rocks and roots on the trail. The asymmetric speedlace closure stays clear of the drivetrain and adjusts easily on the go. Underfoot, the revised X2 Flat outsole pairs Vibram XS Ride rubber with a zone-specific lug pattern - lower midfoot lugs lock onto pedal pins, taller heel and toe lugs dig in for hike-a-bike traction. Features GORE-TEX Invisible Fit membrane delivers waterproof, breathable protection in a lightweight, low-profile construction that doesn't add bulk Updated wider fit in the metatarsal area for more toe freedom and greater comfort on long days riding or pushing the bike Lightweight ripstop upper with wide PU-laminated panels for added durability and protection, plus a reinforced toebox to guard against rocks and roots Perforated Airprene bootie construction replaces a traditional tongue for a pressure-free fit with improved breathability and faster drying after wet rides Asymmetric speedlace closure routes away from the drivetrain and locks or releases quickly, even mid-ride Revised X2 Flat outsole with Vibram XS Ride rubber compound and zone-specific lug pattern: lower midfoot lugs grip pedal pins securely, taller heel and toe lugs provide traction on hike-a-bike terrain Flat pedal compatible - no cleat compatibility Weighs 375g (size 42, single shoe)SPECIFICATIONSUpper Material Ripstop fabric with PU-laminated panels and perforated Airprene bootie Waterproofing GORE-TEX Invisible Fit membrane Closure System Asymmetric speedlace Outsole Vibram XS Ride rubber compound (X2 Flat)Outsole Type Flat pedal Cleat Compatibility N/AFit Regular (wider metatarsal area)Weight375g (size 42, single shoe)Intended Use Gravel, Trail, Bikepacking Sizing EUUSFoot Length (mm)364 1/4230mm375 1/4237mm37. 55 1/2240mm386243. 5mm38. 56 1/4247mm396 3/4250mm39. 57253. 5mm407 1/2257mm40. 58260mm418 1/2263. 5mm41. 58 3/4267mm429270mm42. 59 1/2273. 5mm439 3/4277mm43. 510280mm4410 3/4283. 5mm44. 511287mm4511 1/2290mm45. 511 3/4293. 5mm4612297mm46. 512 1/2300mm4713303. 5mm4813 3/4310mm | Fi'zi:k | Terra Ergolace Flat Gtx 2 Shoes Men's | Size 43. 5 In Black-Black | Rubber
