i was challenged to step on thones. i think it is a harder challenge then stepping on glass, but not as dangerous, the thornes piercing my skin and entering my meat, it not feels nice. maybe in 10 years i will have enough hornskin to dance on it and just break the thorns ;)

Good challenge !

Compliments !

The thorns piercing also your heels ?

Notice that the thorn you step over are quite small,but real true barefooters populations are able to step over bigger one,like you can find on jungle...

For "beat/broke the thorns" you must develop more very hard callous on your soles,but you not need 10 more years.I think that with the needed training you will do it in 5/6 month (or maybe less).
