I've been running marathons in traditional thick sole shoes (Asics Nimbus) for five years with no problems but when I started Crossfit in December I found out that they aren't good for lifting. After researching online and talking to people at our Crossfit I settled on the Inov-8 F-lite 195. While I haven't run long distance in them yet, I do find them quite comfortable for 5K distances and lifting. I am working up to longer distance on the advice of experts.
This pair of shoes together is lighter than a single one of my Asics, but still feel stable and comfortable. They seem to be really well made. I always buy 1/2 size larger than dress shoes to allow room for my toes when I run and that seems to be working well with the Inov-8's too.
So far, so good!
