Thanks for the email. We have actually seriously looked into military branch licensing over the last few years. To be honest we ran into a few snags.
1. Every branch's licensing rights are held by a different party. That means multiple contracts and licensing administration which is a big challenge for our small team.
2. When we were serious about it a year or so back, we spoke to the folks at our company that were in the military and they told us that they would much prefer to be wearing the logo of their unit, not just (e.g.) the Army star. When we started to look into the unit logos, we discovered their were literally hundreds and the detail on many of them far exceeded the capabilities of the stitching area on the back heel of MyJoys shoes (1.25" x 1.25").
Not saying we will never do it, just that when we weighed the ROI, we felt that golfers could get close to what they wanted with color and monograms already available in the program.
