These shoes aren't completely like dunks, but they kind of are in terms of what people are looking for when they want a "dunk-alike": cushioning, general fit, paneling
Joslin 2, Marana, Veer (thinner Ishod Dunk feel)
Es Accel Slim (super thin forefoot without a thicker/supportive insole) & Accel Slim Plus (priced closer to a Dunk usually though:/ but still a pretty comparable dunk knock off)
Es Silo, Accel OG (clunkier than the Accels of 10+ years ago though)
Fallen Patriots (I know it's Fallen, but they're something)
DC: Maswell, Penza
Proper Skateboarding: Cinex, Rook (soles are much thinner than dunks, specifically under the forefoot)
NB# 440 but they're lower cut on ankles
Converse (not Cons) Rival (low and high)
Adidas Tyshawn (minus the dunk paneling, but supportive elsewhere like dunks usually are)
