I got an itab for my first ever marathon medal. Massively over priced. Did it in 3:45:21 and I didn't need to look at my medal to find that out. Like others have said you remember the important ones. Although when I die and my grand kids are checking my medals out they might like to know!
I am been a bit too harsh on the flyknit, just when I went from the normal 3.0 to the flyknit they caused achillies pain! but I think if I went 1/2 size up over the old style 3.0 the flyknit versions might be OK, just think the cuff is a bit too tight. But it's a £100 gamble, that I've lost once already.
As others have suggested if you can try them on do, the free range is/ was the most comfortable running shoe in the world IMHO...
@VDOT52 I've tried a couple of pairs of Sketchers and a pair of kinvara's not keen on either also got some Adidas Takumi Sen's, which I like but find a little narrow.
The 4.0 is the only one worth having at the moment. The 3.0 used to be lovely but then they made them with the horrible flyknitt rubbish... arghhhh... I hate you Nike for doing that. Still haven't found a replacement half marathon shoe.
