Rackets get stiffer. Strings get livelier. Courts get faster. The shoe conversation stays the same.
Does it roll? Does it go flat? Is the rubber still there in month four?
Clay
You need a slide you can finish and a stop you can trust. Dust should not glaze the outsole in a month.
Hard court
You need rubber that survives sandpaper. Lateral support that doesn't roll when you plant. Cushioning that soaks up the pounding without killing court feel.
What we are not doing
We are not building a fashion sneaker with a tennis stripe. We are not building a tank you have to drag around the court. Tennis first. Everything else waits.
The future of the shoe is simple. Hold the point. Last the season.
