I don't know where I've been for the last few years, but I've finally got a pair of KSOs and wanted to try this all out. The concept makes sense to me intuitively, save the difference between concrete/pavement/asphalt surfaces and trails/more natural surfaces.

Anyway, I did a little short recovery run for the first time in them and had some definite pangs of pins and needles/PF in my left foot. I decided not to overdo it and ended up jogging about a mile or so and walking another 1.5 miles, gingerly because of the foot pain.

I went out again this morning on another recovery run, and it definitely felt better. I did about 3 total miles at around 8:30 pace, which is slow for the distance for me, but I definitely don't feel yet like I can go all out on 3 miles in these, unlike in my shoes. There was a slight hint of pins and needles in my left foot, but it never fully flared up on me, which I think is progress.

How slowly is it recommended to increase 'barefoot' mileage? In shoes I'm running 30-50 miles per week, with my long runs around 15-18 miles. Any advice from experience would be appreciated!

Little update: I was feeling the hint of a pre-plantar fasciitis (no real symptoms yet but I'm getting good at noticing it), so I decided to start with some walking and see how the foot felt. It was okay, so I broke out into a little jog which quickly turned into a pretty fast run (for still adjusting to the VFFs). It felt GREAT. So light. I ran back home the same way and felt just fine. Now I have to be very patient about slowly increasing mileage in these things. I wonder how long it will take me to make it to distances that I'm currently doing in shoes (16-18 miles).
