As of my last update, there doesn't appear to be a specific model called "B Icon 2 AG" tennis shoes by Diadora. Diadora is known for its soccer footwear and may not have a tennis shoe line under that exact name. It's possible that there has been a new release or a regional product line that isn't widely recognized.
For accurate information, I recommend checking Diadora's official website or contacting their customer service directly. They can provide the most current details on their tennis shoe offerings and whether a model like the "B Icon 2 AG" exists in their product lineup.
