I'm training for a marathon (3rd one in as many years) in September. Putting in 40-50 miles per week currently. I'm using a pair of Inov8 Road X233's for my runs of <10 miles, and a pair of Kinvara 3 for longer runs, since they are a bit softer. I really like both shoes, but I am absolutely destroying the lateral outsole on my Kinvaras, and at their current rate of wear, there is no way they are going to remain intact until my marathon rolls around. As such, I am thinking of setting the Kinvaras aside, for the most part, until race day, and replacing them with something a bit more durable for my long runs. I am wondering what shoes people would recommend - I would like something relatively lightweight and lower drop, but with a more durable outsole.
Two shoes I was looking at are the Mirage 2 and the NB 890V2. However, Mirage 2's seem to disappearing lately, and I don't know if want to pay full price for the 3, plus I'm not sure how much more durable they would be (since it looks like the lateral outsole is still mostly EVA). The 890V2 looks pretty good, although the differential is a bit more than I'd like; however, I will naturally forefoot strike even in 12mm drop stability shoes (seriously) so it might not be that much of an issue.
I would appreciate any advice on what shoes I should get. As an aside, while I have pretty much eaten my Kinvara's soles for breakfast, the Inov8's soles are just fine, and it doesn't seem to have any more wear on the lateral side of the sole than anywhere else, so it looks like I might be landing more evenly on them than the Kinvaras. Anyone know why this would be?
Thanks for the help!
