Frye leather lovers, it works! I didn't even need a stretcher. I sprayed the inside of my Melissa, side zipper, buttons, used a regular boot shaper. Boom! 12 hours later I could wear the boots with my cord jean jeggings tucked in. I did not massage this into the leather I simply sprayed down the inside zipper, wiped excess an put the shapers in E to W. Love my boots, if you love Frye, you know. I wore my boots for more than 8 hours, first ever wear. It works, buy for all leather I recommend it.See full review
