  • 216. Built to Move: Why Toe Space Matters | Rachel Ridgeway
    Mar 17 2026

    What if the missing piece in better movement and healthier feet isn’t your shoes at all?

    Dr. Andrew Fix sits down with trainer and Aira Basics founder Rachel Ridgeway to unpack a surprisingly overlooked factor in foot health: socks. After switching to barefoot-style footwear, Rachel noticed less discomfort in workouts and a very different physical experience during pregnancy. One question kept surfacing. If shoes can reshape the foot, what role do socks play?

    That curiosity led Rachel to design a sock that respects the natural shape of the foot without forcing people into toe socks. She shares the behind-the-scenes process of bringing the idea to life, from fabric blends to seam placement and durability testing. The goal was simple in theory but complex in execution: create a sock that allows the foot to spread and move without sacrificing comfort or everyday practicality.

    Andrew adds the clinical lens throughout the conversation. The foot contains dozens of joints and muscles that influence balance, strength, and movement across the body. When those structures spend years compressed inside narrow footwear, what changes in the knees, hips, or back? This discussion invites a closer look at a small design detail most people overlook and asks a bigger question about how everyday choices shape long-term movement and health.

    Quotes

    • “Socks were kind of the next piece of that puzzle.” (06:17 | Rachel Ridgeway)
    • “You got to look at your socks because socks can be just as restrictive as shoes.” (06:22 | Rachel Ridgeway)
    • “I feel like this is a product that needs to exist. And I think it'll resonate with people who are in the barefoot shoe world or not, that just want a sock that's a little bit more comfortable, doesn't feel like it's restricting your foot quite as much.” (08:47 | Rachel Ridgeway)
    • “It was really hard to not want to only wear those because I think once you feel that freedom it’s hard to go back.” (14:37 | Rachel Ridgeway)
    • “I like that if it naturally mirrors the shape of your foot, it's going to feel more comfortable.” (45:38 | Rachel Ridgeway)

    Rachel’s Bio:

    I am the founder of a brand new barefoot sock company called Aira Basics. The idea started because I was unable to find comfortable, non-restrictive socks that worked for my whole family. While plenty of toe sock brands exist, there are not many foot shaped brands. None of the brands at the time were in the US either, so I wanted to make an affordable and accessible option for people who wanted a better sock option for their family.

  • 215. Plans are Fragile
    Mar 10 2026

    Your plans may look perfect on paper, yet preparation is what determines whether your goals survive the moment real life hits.

    In this short solo episode, Dr. Andrew Fix reflects on the gap between planning and preparation. Many people enjoy creating plans because they bring clarity and structure. Yet plans often fall apart when circumstances change. Preparation is what makes those intentions durable. It turns ideas into systems that hold up when life gets messy.

    Dr. Fix explains that planning creates direction, but preparation removes friction. A simple example shows the difference. You may intend to eat healthy during the week. If lunch arrives and nothing is ready, convenience usually wins. Preparation removes that last-minute decision and supports the outcome you wanted from the start.

    The conversation also highlights the value of action. People who begin doing often move ahead faster than those who spend endless time refining a plan. Experience grows through action, and momentum builds through small steps. Outcomes remain unpredictable, yet we always control the inputs.

    So where do your goals live right now? On a list or in real preparation? Dr. Fix challenges listeners to move beyond planning and invest in the habits, systems, and actions that make progress possible.

    Quotes

    • “Plans are fragile and preparation is durable.” (02:11 | Dr. Andrew Fix)
    • “Convenience is king a lot of times.” (03:05 | Dr. Andrew Fix)
    • “Planning is more the idea creation. It's the logistical figuring out what the details could be.” (05:31 | Dr. Andrew Fix)
    • “Preparation is the action of putting those plans into place, like actually taking steps to put those plans into action and start making moves based on the plans that you had laid out.” (05:38 | Dr. Andrew Fix)
    • “We don't control the outcomes, we control the inputs and we can look at preparation as inputs that we are investing in what the outcomes going to be.” (07:49 | Dr. Andrew Fix)

  • 214. Choosing the Perfect Mattress for You | Derek Hales
    Mar 3 2026

    Your mattress may be the most important performance tool in your life and most people are choosing it based on marketing instead of measurable impact on sleep, recovery, and long-term health.

    Sleep drives everything. Cognitive sharpness. Physical recovery. Emotional regulation. Longevity. Yet most people approach mattress shopping with guesswork and brand promises rather than clear performance criteria. Dr. Andrew Fix sits down with Derek Hales, founder of NapLab, to unpack how better sleep starts with better decisions about what you lie on every night.

    They move past hype and focus on outcomes. Are you waking up sore? Do you feel restored in the morning? Is your mattress actually supporting your body type and sleep position? Derek shares practical insights from testing hundreds of mattresses and consulting with thousands of sleepers, including why medium-firm works for most people, how couples can solve conflicting firmness preferences, and why mattress weight may be one of the simplest indicators of build quality.

    The conversation also highlights overlooked factors such as foundation support, pillow height, and how different sleep positions affect spinal alignment. The bigger takeaway is clear. If sleep is the foundation of performance and health span, then your mattress is not a casual purchase. It is infrastructure.

    Quotes

    • “If we're not getting good sleep and the mattress is the cause, we need to get a solution.” (05:09 | Derek Hales)
    • “I really don't think there is a sort of best mattress for everybody. There is the best mattress for you.” (07:11 | Derek Hales)
    • “Sleep is the healer. It's how the body restores itself, and how the body recovers.” (12:48 | Derek Hales)
    • “When you sleep deeper, longer, better, health outcomes are better, physical outcomes are better, emotional well-being is better.” (19:02 | Derek Hales)
    • “Sleep is the foundation of our health.” (21:50 | Derek Hales)
