I was thrilled to pieces when I got my Revival.us 16th Century slashed shoes.
These have a quality hardened leather sole. For my tender footsies, I have opted to insert an insole for padding as I do tend to be on my feet a lot when at events. A tiny corner of the insole does show in the slashing on the inside of the foot, but not enough to be terribly distracting - I could also darken the insole with a sharpie to make it disappear into the black leather if it bothered me.
One issue with the hardened leather sole is that it is very slippery. I am a known clutz, so this is a dangerous thing for me. I picked up some non-slip grip pads from a drug store that have a sticky backing and stuck them to area equivalent to the balls of my feet. This helped the slippery factor significantly, but I have noticed that they fall off/disappear over the course of every event I've worn them at. I don't want to keep incurring the cost of re-applying new sole-grippers every weekend. Back in my dance days, if we were about to go on a stage that was particularly slippery, we'd slap a piece of duct tape on our shoes to help grip... not sure how well that would work here, and it seems a bit ghetto. So I'm in search of a long-term solution.
All this aside, I'm very pleased with the quality and workmanship of the shoes, and would definitely try another style from this company.
