I intended to separate the two post, not to create confusion between the two themes. :-)

If we imagine a contest (like the one I've proposed in my previous post, or however another "barefooting contest") among ALL of your girls, well ... the competition WOULD NOT EXIST at all, to me. :-)

My two cents are undoubtfully on NATASHA, the first model.

She has a very strong foot structure, she's a good barefooter with right movements (weight distribution) to deal with stones, and she has and a good attitude (it's observable in her videos, when she steps onto something rough).

But she also has a bad vulnerability: an evident (from pictures) exposed internal soft arch.
It's a vulnerabily very hard to overcome ... maybe impossible at all. Neither "barefoot determination" can supply: pressure in the soft arch can be quicly absorbed by the point of view of mere pain (differently from heel shocks, for example), but deprives the barefooter of strengths, in a sudden way, leaving him/her weak and vulnerable.
Anyone of us can experience it. :-) And Natasha's (wonderful) videos show it: she's great onto sharp gravel, but she suddenly vacillates onto HIGHER (even if not sharp) rough elements ... she goes into trouble, beginning to stare the ground (while she's completely self-confident onto gravel) and feeling vulnerable so to completely loosing the right movement.

However, she remains the strongest here, to me.

But I've a word to say: MARINKA.
Gosh, her feet are simply ... made to be bare, without a single real evident weak spot.
Yep, I'm saying that the ... "less barefoot one", not into barefooting at all, could beat, to my opinion, one of the strongest real barefooters appeared during last years on the whole WWW.
It would be very thrilling to verify, but, I think, it'd completely impossible. :-)

Bye,
