The Nike Vomero 18 features a standard lace-up design allowing for easy adjustment to achieve a secure and personalized fit. Ensure laces are snug but not overtight to prevent pressure points. These shoes are specifically designed as road running shoes and are optimized for paved surfaces and treadmills; while they may handle light, non-technical trails, their primary compatibility is with roads. For care and maintenance, the upper is made of textile and synthetic materials, and the sole is synthetic rubber. To clean, gently wipe away dirt with a damp cloth and mild soap. Avoid harsh chemicals or machine washing, as this can damage the materials and cushioning properties. Allow shoes to air dry naturally, away from direct heat sources, to maintain their shape and integrity. Regular cleaning will help preserve the shoe's appearance and performance over time.
