It’s literally saving shoes and feet across the internet.

“I have had issues with corns and bunions for years, so new shoes, old shoes have become such a problem. I can’t even wear heels anymore. I’ve tried everything, and nothing worked until this,” one Amazon reviewer wrote.

The key to achieving the perfect stretch, according to the reviewer above, as well as others, is to spray the shoe liberally in the areas where you need stretch. Then, put the shoes on (many people claim to opt for wearing the shoes with socks during this process) and walk around in them for the day. You may need to repeat this process a few times, depending on your shoes and the amount you need them to expand. There are also adjustable shoe stretchers available if you don’t want to spend the day in your shoes.

“Arthritis in feet - MIRACLE SPRAY. I have arthritis in both feet with the right foot being worse/bigger from previous gout. I bought real leather shoes for a 1920s themed party but for years have had issues with the tops of shoes being painfully tight. I got my super cute t-strap shoes, tried them on and to no surprise they HURT. And I mean, feet-on-fire-can’t-stand-up-for-longer-than-5-minutes hurt. I saw this spray as a much more affordable option, but was extremely skeptical so I did research and check reviews across multiple sites. I decided to go ahead and try it out. I decided to try the wear-with-socks method. I sprayed, rubbed and wiped and walked around my house a bit. OMG!!! IMMEDIATE results!!! Within 5 minutes, I could feel relief! Not 100% but waaaaaay better than it was. I took them off and did another coat with the balloons again focusing on the sides where it burned and pinched the most even after the last spray because of the swelling. I will check again tomorrow and if still no improvement I will have to assume the shoes have reached maximum stretch but I HIGHLY recommend this spray (at least for leather). It is 100% worth it!” —Lisa Johnson (This review has been edited for length and clarity. Read full review.)

“I had bought a pair of leather boots two years back but they pinched my feet so terribly that I was almost ready to give them away or sell them on marketplace. Wasn’t too hopeful but thought I’d give this product a try. So so glad I did! Sprayed it on and wore the boots with a thick pair of socks. The boots were so tight, they were painful to walk in. Had to use the spray a couple of times but now they are all stretched out and I even have the space to wriggle my fingers. So glad I bought this.” —Gargi CD

“This saved my shoes. Ordered shoes online that are absolutely perfect for the gown I’m wearing to a black tie wedding. But... so tight they were making me scream after 5 minutes on my feet. So I generously sprayed the inside of each shoe. Then with ankle socks on my feet, wore them in my house for a couple of hours. When I removed the socks, the shoes were a tiny bit better, but still too tight. So I repeated the above and wore them for two more hours. (Yes, I looked silly, but what we won’t do in the name of glamor.) Guess what - the second try was the charm! I can now wear these gorgeous shoes with no pain.” —Joyce

“A real life saver for tight shoes! This shoe stretch spray really works! I used it on a pair of leather shoes that were too tight, and after spraying and wearing them for a bit, they fit perfectly. It softens the material without damaging it. Such an easy fix and a total lifesaver—highly recommend for anyone with snug shoes!” —Louna
