Very similar cracks along the same area, happened to both sides of my 09 eggplants but I noticed it after a goooooood year+ of regular use(99% casual wear, played in em outdoor 5X, but playin OUTDOORS in foams destroys the grip/soles extremely fassssst).
If you're worried about performance or further problems due to that tear and you're only using those for casual wear, you can rest easy, however if you want to use them for playing in, or if you're constantly tightening/loosening your laces, you will potentially make the tear worse.(i keep my laces pretty loose all the time) You'll be able to wear those things for yearssss of casual use even with that slight tear/crack, and the grip on the soles will probably wear down faster than that area does over time, so keep rockin emmm cause they still fresh to death...imo
