When ordering shoes, you must prioritize material quality and construction methods. For leather shoes, verify if it is Full-Grain, Top-Grain, or PU/Synthetic leather based on your target price point. For athletic footwear, focus on midsole technology (EVA, TPU, or ETPU) for cushioning and outsole abrasion resistance (DIN standards). Ensure the Last (the foot mold) is adjusted for your target market's specific foot morphology (e.g., Western vs. Asian sizing) to avoid high return rates due to fitment issues.
