Where Are Your Shoes? Turning Family Conversations Into Diabetic Foot Surveillance | LIMBWatch with Jonathan Brocklehurst

In this episode of LIMBWatch, Dr. Gabrielle Hutcheson Donaldson sits down with Jonathan Brocklehurst MSc, MIRL, MRCPod, HCPC Registered Podiatrist, wound-care specialist, educator, and author of Grandpa, Where Are Your Shoes? for a powerful conversation about one of the most overlooked components of limb preservation: early observation and prevention.

Jonathan shares the journey that led him from podiatry and amputee care to wound healing, health literacy, and ultimately writing a children’s book designed to make diabetic foot education accessible across generations. At the heart of the conversation is a deceptively simple question:

“Where are your shoes?”

Jonathan explore how footwear can provide clues about what is happening to the foot—from abnormal wear patterns and pressure to rubbing, deformity, instability, and potential sources of tissue breakdown. They discuss why people living with diabetes and neuropathy may not feel injuries developing, making daily visual inspection of the feet and shoes particularly important.

But this episode goes far beyond footwear.

Jonathan explains why children and family members can become important partners in diabetic foot surveillance without becoming amateur clinicians, and how simple conversations at home can help reduce stigma, isolation, and health-literacy barriers. The discussion explores the powerful relationship between grandparents and grandchildren—and how a child’s seemingly innocent question can open the door to conversations about diabetes, neuropathy, footwear, prevention, and seeking professional care.

The conversation also tackles health equity and footwear affordability, emphasizing that effective diabetic foot prevention must account for social determinants of health and the realities of patients’ lives outside the clinic.

In a rapid-fire finale, Jonathan addresses some of the biggest misconceptions surrounding diabetic feet, including the dangerous idea that “if it doesn’t hurt, it isn’t a problem.” He also shares practical advice on daily foot checks, footwear, hygiene, and avoiding potentially harmful DIY foot care.

Ultimately, this episode asks us to rethink diabetic foot surveillance. It doesn’t always begin with advanced technology or a wound—it can begin with a question, a pair of shoes, a family conversation, and someone noticing that something has changed.

Because sometimes, limb preservation begins at home.

Where are your shoes?
Check your feet. Check your shoes. Protect every step.

In this episode Dr. G explains pinch grafting — a simple autologous technique that places tiny pieces of a patient’s own skin onto a prepared wound bed to create epithelial “islands” that promote closure. She covers the history of the Reverden graft, the biology of graft take (plasmatic imbibition, inosculation and neovascularization), and how epidermal islands accelerate re-epithelialization.

The episode emphasizes the critical need for wound-bed preparation, adequate perfusion, infection control, offloading, and systemic optimization in diabetic foot care, compares pinch grafts to split-thickness grafts, and outlines indications, common causes of failure, and the role of grafting in limb salvage.

This episode of Diabetic Foot Files shares ten practical habits to prevent serious foot problems and limb loss in people with diabetes. The host emphasizes vascular assessment as the top priority and walks through daily foot checks, never ignoring small wounds, checking shoes, wearing proper footwear, protecting feet from heat, avoiding home surgery and soaking, taking toenails seriously, knowing personal risk, and having an action plan for problems.

Listeners will learn simple, actionable steps to spot issues early, seek prompt professional care, and preserve mobility and quality of life.

Dr. G explains how type 2 diabetes can develop quietly and describes common but often overlooked early signs — persistent thirst and urination, fatigue, blurry vision, recurrent infections, slow-healing cuts, numbness in the feet, increased hunger, and unexplained weight loss.

The episode also covers how diabetes is diagnosed (A1C, fasting glucose, and glucose tolerance tests), who should be tested, when high blood sugar becomes an emergency, and why regular screening and early detection matter to prevent serious complications.

Dr. G uses the giraffe-in-quicksand metaphor to show how clinical inertia and tunnel vision quietly worsen diabetic foot ulcers. Clinical inertia isn't doing nothing—it’s doing too little: repeating dressings, documenting instead of investigating, or delaying referrals.

She outlines four types of inertia (diagnostic, therapeutic, referral, cognitive), stresses multidisciplinary care, and gives clinical pearls: "stable" ≠ healing, always reassess diagnoses, address blood flow, infection, nutrition, and adherence, and prioritize curiosity, humility, and collaboration to prevent limb loss.
