It depends on the type of adidas shoe. CLB 2016 was a half size down, CE 2016 Neoprene and Primeknit TTS, CE Low Primeknit 2016 Half size up, Dame 3's Half size down and Rose 7's TTS. CE 2017's run a half size small. My feet are normal width but as they say, everyone's foot isn't the same but sizing in general is a huge problem with Adidas so if you can try on before buying that's the way to go. Champs and Foot Lockers have been getting CE 2017's in.
The outlet near me had a pair of CE 2017's on red tag for $89 but they were beat up. Last pair from what they got right when they came out. Sales are half off red tag items as well as 30% off during this Labor Day weekend so those CE17's are $45. Also DRose 7 Arthur Ashe Tributes $77 and CE 2016's Neoprene's $77. Also been seeing CE 2016 Neoprene for $50 in Burlington Coat Factory but size 12 and up.
