atomic nuke 130. i have tried on alot of 98 millimeter lasted boots and this i the narrowest i have found. the krypton, nordica jah love, full tilt, lange banshee pro and technica agent 130 were all to wide for me but the nuke fits me great. it is very narrow all the way through, especially in the heel/instep area. this boot is basically the Atomic RT Ti Race 130 boot. the only difference is the shock absorbing boot bed and the giant syncing power strap.
well for one dont get the Moro's as they are soft, far softer than the rampages. Take a look at the Full Tilt Seth Morrison boots they are pretty dam stiff but still have a nice even flex unlike many of the 98 last race style boots.
