I've been wearing asics gt-1000s for past 3 years. The GT-2000 are much more narrow...they pinch my toes after one day of use and are causing the pinched nerve I had removed from my foot over 15 years ago to flare up. First pair of shoes that have ever done that. I could wear my gt-1000s for a 16 hour shift and my feet and legs wouldn't hurt at all. I've worn these for 12 hours now and my legs ACHE all the way up to my a$$. Spend your money on a better made product
