Steven ★★★★★ Oct 18, 2026

My work boots used to smell like a locker room by Thursday, but after a week with these yellow insoles, the odor is genuinely gone. The cushioning is firm yet springy, and they slipped right into my size 9s without any trimming.

The probiotic tech is no joke—I’ve worn these insoles for two weeks of yard work and my boots still smell fresh. They slipped right into my size 9 boots and the extra cushioning makes a real difference on concrete.

Swapped these into my work boots after a long shift on concrete and my heels stopped aching by day two. The probiotic layer actually keeps them from getting that sour smell, which I didn't expect to work. Medium fits my size 9s perfectly.
