High-Quality Insole!

I replaced the smelly worn-out insoles in my pickleball shoes with this high-quality Purra insole. So far, they’ve been a game-changer. I’m less sore after exercise and the hygiene factor is a winner.

I just switched to these insoles in my trail running shoes and I'm already hooked. Impact protection is phenomenal and my feet don't feel as torn up.

Tess

Verified Customer

Something about the spheres in these insoles that just makes my feet feel great. I have a pair in my Peloton shoes now for odor protection, and also have another in my court shoes as I just love the extra boost I feel - along with less knee joint pain.

Shawn

I'm a gym rat and my shoes are worn and ripe. Antimicrobial odor protection is a must for me, and these insoles are spongy & comfortable. Great purchase!
