I just reviewed the Invisible Shoes/Xero Shoes Connect, and I had a weird moment while running in them. I was on some especially rough pavement (the type of stuff that is miserable barefoot) and even through the 4mm sole it was still a bit uncomfortable. I caught myself silently complaining that there was too much groundfeel. As someone who has spent the last three years sanctimoniously complaining about the insufficient amount of groundfeel in every piece of footwear I've tried, I feel like I've betrayed something. Do I even deserve to call myself a barefoot runner anymore? Have I lost my moral superiority over heel strikers? Do I even have the right anymore to preach to total strangers about the evils of arch support and the Nike plot to keep the masses in a constant state of injury?
