I ran the marathon in the Nike Vaporflys on Sunday and my legs actually feel pretty fresh afterwards. I was a bit sore with DOMS for a couple of days but feeling back to normal today and just been out for a nice recovery run. It's a stark contrast to last time when I ran in Asics Gel-Nimbus and it absolutely trashed my legs. One of my knees was injured for weeks afterwards and had to stop running for a while. Whatever your opinion is on these super shoes they do seem to be very good at looking after you during a marathon. That alone makes them worth it for me.
