Running

Was very tempted to order a pair of kayanos (tis the true king), but I've only been comfortable in the wide versions of asics shoes, and heard that they narrowed to toe box of kayanos recently. Brooks trance were also high on the list, but I've never owned a pair of Brooks so was unsure of fit (ordering online, unwise I know). It came down to my ever favourate Mizuno Wave Nirvana, or the newish Saucony Grid Paramount (both Saucony and Mizuno fit me well). Went for the Saucony, as I fancied trying something new.

its usually around 300km for foam based running shoes
but in different systems eg nike air.nike shox it varies due to the elasticity
and impact resistance of the sole and various other components
im not a running expert but im a trainer nerd haha

Back in my prime running years I was doing nearly 50km a week thats a new pair of trainers every six weeks. That cant be right?
