My gym bag smelled like regret for weeks, but after tossing a couple of these inserts in, it’s genuinely neutral within a day. The moisture absorption is what sold me—no more damp sneakers after a rainy commute. One set’s been going strong for over a month, so the freshness definitely lasts.

The fact that these do double duty—soaking up moisture while killing the smell—means my gym bag finally doesn’t need airing out for a week. I tossed three in my hiking boots after a rainy trail day and the musty odor was gone by morning, with a fresh scent that hung around for days.

The orange geometric design looks sharp peeking out of my work boots, and these inserts actually pull the dampness out after a rainy commute. My boots smell fresh days later, which is more than I can say for the last pack I tried.
