Vintage Sidi "MC Touring" Model boots.  - Sz 6

I believe these may be the first model of touring boots that Sidi ever made, from the first or second year that the company started making motorcycle boots.  Attached in the photos is an ad of the product lineup for 1971, and the touring boots in the photo have "Sidi Sport" embossed at the top of the boot shaft. 
Thee boots do not have that feature, so I would guess these boots came before the 1971 Model shown in the ad.

New/unused vintage boots with original box.   The outsole of the left boot shows some warping.  Not sure if this would correct itself with some use.  There is no sign of separation of materials or other damage to the area.  This area is shown in the last 3 photos.
