The 2012 Adipower are the best Oly shoe I've had to date. Initially I was worried that with only 1 strap, my feet wouldn't feel secure and the shift away from the wood heel would not be as solid. I can you that, my feet have never felt more secure. The heel is incredible and literally locked in. For $136 and free shipping, it is a must buy if you guys squat regularly. Trust me, you will see PBs if you've been squatting with cross trainers. You will never go back. This is assuming you're high bar squatting. I'll admit that I prefer chucks for low bar PL squats.
The tongue also stays put - which was always an issue with the old Adistars which had a habit of shifting to either side. If I had to rank in order:
2012 Adipower
2008 Adistar
Nike Romaleo 1
The heel is nearly identical. The Adistar heel is quite worn in this pic. I still like the carbon fiber finish. Many lifters commented on durability issues but I've had no issues. Training sessions are normally 2.5hrs 5-6x a week.
