How Peripheral Artery Disease Affects the Feet

Tuesday, 10 February 2026

Peripheral artery disease, or PAD, occurs when narrowed arteries reduce blood flow to the legs and feet. This most often develops from plaque buildup along artery walls, which limits oxygen delivery to tissues. Poor circulation can cause symptoms such as leg cramping with walking, cold feet, slow growing toenails, or skin that appears thin and shiny. In more advanced cases, wounds may heal slowly or not at all. Risk factors include diabetes, smoking, high blood pressure, high cholesterol, and increasing age. Treatment focuses on improving circulation and reducing complications. This may involve lifestyle changes, medication, wound care, and close monitoring of foot health. Early detection is important because reduced blood flow increases the risk of infection and tissue damage. If you notice persistent leg pain, changes in foot skin, or slow healing sores, it is suggested that you see a podiatrist for a proper diagnosis and appropriate treatment.

Peripheral artery disease can pose a serious risk to your health. It can increase the risk of stroke and heart attack. If you have symptoms of peripheral artery disease, consult with Gregory T. Loo, DPM from Elite Podiatry. Our doctor will assess your condition and provide you with quality foot and ankle treatment.

Peripheral artery disease (PAD) is when arteries are constricted due to plaque (fatty deposits) build-up. This results in less blood flow to the legs and other extremities. The main cause of PAD is atherosclerosis, in which plaque builds up in the arteries.

Symptoms

Symptoms of PAD include:

Claudication (leg pain from walking)
Numbness in legs
Decrease in growth of leg hair and toenails
Paleness of the skin
Erectile dysfunction
Sores and wounds on legs and feet that won’t heal
Coldness in one leg

It is important to note that a majority of individuals never show any symptoms of PAD.

Diagnosis

While PAD occurs in the legs and arteries, Podiatrists can diagnose PAD. Podiatrists utilize a test called an ankle-brachial index (ABI). An ABI test compares blood pressure in your arm to you ankle to see if any abnormality occurs. Ultrasound and imaging devices may also be used.

Treatment

Fortunately, lifestyle changes such as maintaining a healthy diet, exercising, managing cholesterol and blood sugar levels, and quitting smoking, can all treat PAD. Medications that prevent clots from occurring can be prescribed. Finally, in some cases, surgery may be recommended.

Traits of Walking and Running Shoes

Tuesday, 03 February 2026

Walking and running shoes are designed differently to accommodate unique foot mechanics and movement patterns. Walking shoes distribute weight more evenly across the foot, offer moderate cushioning, and typically have a lower, more stable heel flare for balance. Running shoes are built for forward motion, with increased cushioning to absorb impact, a higher heel to support stride, and more responsiveness and flexibility to handle repeated high force. Choosing the correct shoe type reduces fatigue, prevents injury, and supports natural foot function. A podiatrist can assess gait, recommend appropriate footwear, and prescribe custom orthotics if needed to optimize performance and comfort. If you have foot pain, it is suggested that you consult a podiatrist who can treat various foot and ankle conditions, and guide you on the right type of shoes to wear for your desired activity.

If you are a runner, wearing the right running shoe is essential. For more information, contact Gregory T. Loo, DPM from Elite Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Choosing the Right Running Shoe for Your Foot Type

To increase performance and avoid the risk of injury, it is important to choose the right running shoe based on your foot type. The general design of running shoes revolves around pronation, which is how the ankle rolls from outside to inside when the foot strikes the ground.

Neutral runners are able to choose from a wide variety of shoes, including minimalist shoes or even going barefoot.
Runners who overpronate, or experience an over-abundance of ankle rolling, should choose shoes that provide extra motion control and stability.
Runners who underpronate, or supinate, have feet that have high arches and lack flexibility, preventing shock absorption. They require shoes with more flexibility and cushion.

Why Friction Blisters Form on the Feet

Tuesday, 27 January 2026

Foot friction blisters develop when repeated rubbing damages the top layers of skin. This commonly happens during long walks, new exercise routines, or when wearing shoes that do not fit properly. Moisture from sweat softens the skin, making it more vulnerable to injury. As the skin rubs against socks or shoes, fluid collects under the surface, creating a painful bubble. Blisters often form on heels, toes, or the ball of the foot where pressure and movement are greatest. Redness, tenderness, and burning may appear before the blister becomes visible. Although many blisters heal on their own, broken skin increases the risk of infection, especially in people with circulation or nerve issues. Wearing proper footwear, moisture control, and early care can reduce problems. If foot blisters are frequent, painful, or slow to heal, it is suggested that you see a podiatrist for appropriate treatment and prevention tips.

Blisters may appear as a single bubble or in a cluster. They can cause a lot of pain and may be filled with pus, blood, or watery serum. If your feet are hurting, contact Gregory T. Loo, DPM of Elite Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters are often the result of friction. This happens due to the constant rubbing from shoes, which can lead to pain.

What Are Foot Blisters?

A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.

Symptoms

(Blister symptoms may vary depending on what is causing them)

Bubble of skin filled with fluid
Redness
Moderate to severe pain
Itching

Prevention & Treatment

In order to prevent blisters, you should be sure to wear comfortable shoes with socks that cushion your feet and absorb sweat. Breaking a blister open may increase your chances of developing an infection. However, if your blister breaks, you should wash the area with soap and water immediately and then apply a bandage to the affected area. If your blisters cause severe pain it is important that you call your podiatrist right away.

Comfortable Shoes for Employees Across All Professions

Tuesday, 20 January 2026

Wearing comfortable shoes is essential for employees in all professions, whether work involves standing, walking, or sitting for long periods of time. Proper footwear supports the feet, promotes good posture, and helps reduce strain on the joints and lower back. When shoes feel comfortable and sensible, employees are more likely to stay focused, energized, and productive throughout the day. Uncomfortable footwear can lead to fatigue, pain, and decreased performance over time. Comfortable shoes should offer supportive cushioning, stable soles, and a proper fit that allows natural movement. A podiatrist can help evaluate foot health, recommend appropriate footwear, and provide custom orthotics, when needed. If you have foot pain during your work day, it is suggested that you consult a podiatrist who can treat various foot conditions, and guide you on appropriate shoes to wear while working.

While working on the feet, it is important to take the proper care of them. For more information about working on your feet, contact Gregory T. Loo, DPM from Elite Podiatry. Our doctor will treat your foot and ankle needs.

Working on Your Feet

Standing on your feet for long periods of time can cause stress and pain in your feet. Your whole body may experience change in terms of posture, back pain, bunions, callouses and or plantar warts. There are ways to avoid these conditions with proper foot care, smart choices and correct posture.

Positive Changes

Negative heeled shoe – Choosing this shoe type places the heel slightly lower than the ball of the foot. These are great for overall foot health. Find shoes that fit you correctly.

Go barefoot – Our feet were not designed to be enclosed for all hours of the day. Try to periodically expose your feet to air.

Eliminate Pain

Foot Exercises – Performing simple exercises, incorporating yoga and doing stretches are beneficial. This will allow increased blood flow to the area and muscles of the foot.

Achilles tendon – Stretching the foot out flat on the floor will relax the calf muscles and tendon. These exercises can be performed almost anywhere. Make sure you add these exercises to your daily regimen.

With a little bit of this information and knowing more about foot health, you will notice changes. Foot stretches and proper footwear will help with pain and prevent further issues.
