*2026-03-07, version 2.0.1*

This was absolutely the best experience as far as a contest has ever gone for shoe!  This beats any line I would stand in-any raffle I would participate in-any store I would go in-by far way, way far and to be in the top 98% percentile in the end paid off I also learned a lot and my Mars yard 3.0 shoes are stellar and supreme imo - Changed my habits and started new rituals!
