Minimalist shoes with size differences - Vivobarefoot Primus Lite Road Running Shoes - Men's

Over-all this seems to be a great minimalist/barefoot shoe with a thin sole under foot, minimalist construction, and no arch support. I have not had the opportunity to break them in and test the quality of the make yet as the sizing was dramatically not as I expected. I would highly recommend measuring your foot length and ordering based off of that measurement (which would have had me order a size down from my normal).
