How's your gut size? I can lean forward, leaning my torso between my legs and get a moving thrust with my legs to get up from the creeper. It sounds like you need to get a better brand of shoes, too. The two brands I'm wearing now are the standard old British (Made in ROC) Reebok Classics and the Denali (Fabrique en Chine) low walking boots. Their soles last 3+ years of hard use before even thinking of wearing out, and it's usually the little toe area of the uppers which is worn through, because I often sit crosslegged when working at ground level painting or such. The soles are good for eons, and I seldom walk less than half a mile a day, usually 1-1.5 miles.
