I thought of the Goalie Monkey Koho's immediately, too. BUT, that is also a different grade of pad, with none of the custom details like the straps, toe caps or catcher palm. I do see the danger of ignoring a designer's right to control the use of their work but at the same time, if something like this is strictly a one-off that can't be purchased from the original creator, is it actually a deprivation of a sale? I'd say that it's not worth losing sleep over.
However, there are lots of players out there in the market mass-producing rip-off equipment designs/graphics and marketing them as such to undercut the original. I'm thinking the lookalikes to Wright's masks (down to even the names), near clones to the major gear makers pads and gloves. It might be well made, quality stuff but that's not really the point. That kind of thing I am on board with as getting into the scope of predatory copyright infringement. It's a little harder to pin the line down between homage and rip-off with this Kenesky set.
