The 06 torq is a 3/4 boot that uses softer overlay material making it flexible side to side. It still has great heel and toe response and like Jarrod said because the torq uses universal footbeds: s-m, l-xl, xxl, it makes the lower section or ankle section a little wider. To help with a better fit it comes with dual laces.
The Zeus is made of stiffer overlays and is a full cut boot allowing more support through the whole binding. Since the material is stiffer the boot is more responsive overall. The footbeds are individually sized: s,m,l,xl,xxl, so you can get a better fit, along with the dual lace.
