The War on Sneakers, Part II: How Conflict Is Raising the Energy Cost of Making Shoes

War is always first and foremost a human tragedy. It brings destruction, instability, and loss that should never be minimized. But beyond the immediate human cost, conflict also disrupts the systems that keep everyday products moving across the world. In footwear, one of the biggest consequences is rising pressure on the energy inputs behind manufacturing. That matters because shoes are not a luxury for most people. They are essential to daily life, mobility, health, work, and safety. When war destabilizes the energy needed to make and move footwear, the entire market feels it. The Footwear Industry Has an Energy Problem, Not Just a Materials Problem A common argument in the sustainability conversation is that modern footwear relies too heavily on petroleum-based materials. From that perspective, if oil prices rise, the solution seems obvious: switch to natural or bio-based materials. But the issue is bigger than materials alone. The real challenge is energy. Every shoe depends on energy at nearly every stage of production. Materials must be extracted or grown, transported, processed, woven, molded, dyed, assembled, packaged, and shipped. That applies to synthetics, leather, cotton, rubber, foam, and most alternative materials as well. Even products marketed as more natural or sustainable still rely on energy-intensive systems. Cotton requires farming, fertilizer, transport, spinning, weaving, dyeing, and finishing. Leather must be processed and treated. Bio-based inp
