LT-C8QJ818 Breathable Summer Sports Gym Fitness Casual Flat Footwear
Engineered by Quanzhou Lute Footwear Co., Ltd. in Chendai Town, Jinjiang, this barefoot running and gym trainer features a calibrated 0.0mm planar drop and an anatomical 112mm wide toe box that allows uninhibited natural metatarsal splay during high-load squats and deadlifts. The 4.0mm low-profile vulcanized gum rubber outsole (Shore A 60 durometer, DIN abrasion under 110mmΒ³) delivers direct ground proprioception while meeting SATRA TM144 slip resistance standards with a certified dynamic coefficient of friction exceeding 0.58 on contaminated wet tile. Breathable hydrophobic Jacquard flyknit uppers are reinforced with high-tenacity TPU lateral film overlays to secure lateral foot containment without binding the hallux. Backed by ISO 9001:2015 quality management and verified CQC factory credentials, Lute Footwear supports rapid sample prototyping in 3 to 7 business days, flexible private label MOQ starting at 200 pairs per colorway, and high-efficiency container loading averaging 7,800 pairs per 40HQ ocean freight container.
