Scrub extremely

I wear for years regularly Vans and never had the comfort away from the usual run-time problems. This model I have already done once owned and had no problems. This time, however, totally strange: The shoes extremely scrub down at the heel and also still on the big toe towards the inside. Problem is I think extremely hard seams the Vans processed in this model and that make running a few meters to a rather painful affair. This morning I had to turn around and put on my old shoes because the scouring was just too crass to 30 M. I can not say exactly whether the seams others were in earlier models, but something I had never with Vans.
I have blood in my 2-day-old shoes, no idea what's going on, from the problem the way you can read in other online shops. Vllt Vans actually what changed in the production process, as I said my suspicion falls on the seams. As these shoes are first unusable, only one point.
