All three are 'premiums' however due to the disco metallic finish, not all panels are leather. Luckily for us, the non-metallic grey keeps the shoe in check, making it suitable for the streets.
We're unsure if it is a sampling error or calculated deliberation but they are not identical in execution; the Stab air bubble coloration doesn't match it's midsole and the AM90 sports a grey sole - not black, making each shoe slightly different than it's brethren...
