I wore these shoes infrequently and took good care of them, so they are in overall good condition (please check the photos for the condition). The following information is from the On website: Trail running shoes with high cushioning that can handle any surface. Soft landings with Helion™ superfoam and excellent stability with Missiongrip™. For long distances and ultra-running. - Weight: 295g - Knit upper that wraps the foot like a sock - Advanced outsole with 50% more ground contact area - Updated form and stack height for a more comfortable ride - Redesigned collar for improved heel fit and comfort - FlipRelease system for optimal fit adjustment - Elastic band to safely store laces - Softer cushioning for improved support and comfort - Higher heel pad reduces impact on the heel, and internal panels firmly hold the midfoot
