i'm a bit out of the loop now but the equipment is pretty advanced compared to tech deck. 5 ply wooden boards, special trucks, wheels with tiny ball bearings, it's pretty cool
there's a very old app on iOS (and hasn't been updated in ages as well) called Asphaltgold Fittingroom where you can enter your shoe size on a certain sneaker model and then it'll let you know what size you'd need for another model, even across different brands
i use it all the time when buying sneakers that are new to me it's great
i need to see those VWs please
