The Foothold removes all three. Zero drop. A 4mm sole. Room for your toes to actually spread.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThat's it.

Your calves are going to be sore.\u003c\/strong\u003e Roughly the first two weeks. That soreness is muscle waking up, not the shoe failing — but it's real, and every company that doesn't warn you about it is quietly keeping your money when you give up in week two.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e2. This is not a 12-hour-shift shoe on day one.\u003c\/strong\u003e If you stand on concrete for a living, these are your \u003cem\u003eoff-shift\u003c\/em\u003e shoes for the first few weeks. In one MRI study, 10 of 19 runners who switched to minimalist shoes showed increased bone-marrow swelling after ten weeks — and they'd transitioned \u003cem\u003egradually\u003c\/em\u003e.
