I can run and walk in any shoe with these inserts for hours! I’m a server, bartender, runner, and weight lifter that has always struggled with knee issues, tight glutes, and sore feet. These inserts take all the problems away and make every shoe so freaking comfortable! I can wear any shoe with these inserts, stand for hours, and nothing hurts which I didn’t know was possible! They take about a week or 2 for your feet to get used to them- you might be sore in weird places, but I promise you, it’s worth it!
