I was skeptical at first especially since the product says to spray inside the boot and that both pairs of boots i used this on have waterproof gore tex lining

I highly recommend to put on 2 pairs of thick socks spray the inside of your boots and spray the outsides of your boots and then go on a hike or walk outside for about an hour that is what i did and my boots fit perfectly

This spray will not make your boots longer or a whole size bigger also this spray wont make your boots a whole size wider it has its limitations

However if you have boots that are a tad too tight or too narrow or have pressure points where the boot is too tight this spray works wonders
