Fizik Ergolace 2 Flat Shoe Go further, go anywhere The Fizik Ergolace 2 Flat Shoe is a lightweight, versatile off-road shoe built for riders who want to take their bike beyond the pavement. Updated from the original Ergolace with a wider fit in the metatarsal area for more toe room and all-day comfort, plus a streamlined ripstop upper with less bulk and a reinforced toebox to handle rocks and roots. The asymmetric speedlace closure stays out of the drivetrain and locks down fast, even mid-ride. Underfoot, the new X2 outsole pairs a Vibram Megagrip rubber compound with a zone-specific lug pattern - lower and flatter in the midfoot for mechanical pedal grip, taller and more aggressive at the heel and toe for hike-a-bike traction. A nylon shank clip-in version offers improved power transfer for longer efforts. Features Updated wider fit in the metatarsal area for more toe freedom and increased comfort on long days in the saddle or on foot Lightweight ripstop upper with wide PU-laminated panels for added protection and durability, 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 Asymmetric speedlace closure routes away from the drivetrain and locks or releases quickly, even on the move New X2 outsole with Vibram Megagrip rubber compound and zone-specific lug pattern: lower midfoot lugs improve mechanical grip on pedals, taller heel and toe lugs dig in for ground traction on hike-a-bike sections Nylon shank (clip-in version) optimized for stiffness and walkability, improving pedaling efficiency without sacrificing comfort off the bike Weighs 410g (size 42, single shoe)SPECIFICATIONSUpper Material Ripstop fabric with PU-laminated panels and perforated Airprene bootie Closure System Asymmetric speedlace Outsole Nylon composite shank with Vibram Megagrip rubber compound (X2)Cleat Compatibility N/ACleat Adjustment No Fit Regular (wider metatarsal area)Weight410g (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 2 Shoes Men's | Size 42. 5 In Dark Blue-Black | Nylon
