Podiatrist Tested

Video Library: Dr. Tom Biernacki on Feet and Footwear

Every guide on Podiatrist Tested is written by a foot and ankle surgeon. This page collects the video versions: talks from Dr. Tom’s YouTube channel, Michigan Foot Doctors, each matched to the written guide that covers the same problem in more depth. Watch the explanation, then read the shoe or insole guide that goes with it. Every guide linked below also carries its video on the page itself.

Shoes

Every shoe we have written up lives in the review index — each one a spec analysis of the published numbers, clearly marked as not yet bench-tested.

Fit, toe box, drop and cushioning — the features that decide whether a shoe helps or hurts.

Brands and head-to-heads

What the brand is actually selling you, and how the models inside a line differ.

Insoles, orthotics and add-ons

Over-the-counter, semi-custom and custom, plus the pads and spacers people try first.

Conditions

The problem itself — what causes it, what treats it, and where footwear fits in the plan.

On your feet all day

Twelve-hour shifts, classrooms and concrete floors, and the swelling that comes with them.

Kids, toddlers and pregnancy

Feet that are still changing shape, where the usual advice does not apply.

New videos land on the channel every week. Dr. Tom has published more than 1,600 of them to 976,000 subscribers, and the footwear ones feed straight into the guides on this site.
