Lesson 1Upper material selection: knit, mesh, leather, recycled textiles — properties an tradeoffsDis section compare knit, mesh, leather, an recycled textile uppers, focusin on breathability, support, stretch, durability, an cost, so yuh can balance performance, aesthetics, an sustainability inna yuh material choices. It cover comparin knit, mesh, leather, an textile uppers, breathability, moisture management, an thermal comfort, stretch, support, an shape retention inna uppers, abrasion resistance, agin, an care requirements, an cost, sourcin, an aesthetic considerations.
