I went off Fastwitch when they lowered the heel-toe drop from v4 to v5. I PB'd a marathon in v4 but v5 gave me blisters on the arches during a HM. Reading up on these (v7) it seems that they're supposed to be more cushioned and flexible than "previous versions", but still with the same heel-toe drop. I'm tempted to give them another go, perhaps for shorter distance races initially, since they're a fair bit lighter than my Adios Boost. If they're softer, maybe they'll be closer to v4 again, and I can get used to the lower drop?
Where did you get these from, and have you had any experience of previous versions?
run4it.com have Kinvara 7 in stock (£110) in 9.5. They also have Kinvara 6 (£55) if you don't care about colours or last year's model...
Have ordered from run4it before and they were fine.
