It wasn't the brand. It wasn't the style. It wasn't your feet. Standard insoles are engineered for a 150-lb body. When you weigh 230, 260, 300 lbs — you're putting 67% more force through foam that was never designed for your load. It compresses flat in 3 to 6 weeks. Every time. You can't feel it happen. The insole looks fine. But it's dead. And your foot, knee, and back absorb every impact it was supposed to handle. The Foundation is the only insole with a load rating for your weight. That's not a marketing claim. That's a material specification.
