Night Splint for Plantar Fasciitis

Plantar fasciitis is one of the most common conditions we treat in our sports medicine clinic. Inflammation of the plantar fascia causes pain in the heel or the arch.

A hallmark of plantar fasciitis, is pain when you first step out of bed in the morning. If  your first step in the morning is a pain in your heel or arch, you may want to try a plantar fascial night splint.

Plantar Fasciitis Posterior Night Splint – Medium (Colors May Vary)

A plantar fascial night splint is designed to keep your foot at a 90° angle, which gently and continuously stretches the plantar fascia, minimizing contraction, that can cause morning pain.

In our clinic, we recommend patients wear the night splint three hours before going to bed, which is usually effective in eliminating their morning pain. If your pain is not alleviated with wearing the splint before you go to bed, then wear it to bed.

Here’s a video from our FDFAC YouTube channel showing you how to properly use your night splint.

If you think you have plantar fasciitis or some other similar condition, it’s important to seek treatment with your podiatrist, as a delay in treatment may make your condition worse.

Big Toe (Pinch) Callus

At least once a week I treat a runner with painful calluses under one or both big toes. This type of callus is known as a pinch callus and typically goes unnoticed until it gets so thick a blister forms underneath it, or causes pain due to lack of cushioning from the running shoe.

Removing the pinch callus alleviates the pain, however understanding the cause is key to preventing a recurrence.

Today, a runner came in having a pinch callus and didn’t realize the cause was his unsupportive running shoes. When the foot collapses, or pronates, during running, push-off of the big toe occurs on the side of the toe as opposed to the bottom. This in turn creates friction, and when there’s skin friction, there’s callus. Using our scientific gait analysis video software, you can see how this runner’s right foot pronates significantly. This is made worse by wearing the wrong type of running shoe for his alignment.

If you or someone you know suffers from pinch callus, don’t wait until it causes pain. Make an appointment with your Sports Medicine Podiatrist to have it shaved down. Also ask them to check your gait for excessive pronation, which may be the underlying cause.

Sometimes a more supportive shoe is all that’s needed to reduce a pinch callus buildup and sometimes custom orthotics will be necessary to reduce excessive pronation. Either way, pinch callus is not protective and should not be ignored.

Cycling Shoes And Sesamoid Pain

Sesamoiditis is inflammation of the bones beneath the big toe joint.

Cycling can exacerbate sesamoiditis, especially when using clipless pedals (this is because your forefoot is locked in). This system provides a more efficient stroke for bikers, but if the cleat is in the wrong place or the last (shape) of the cycling shoe is different than the riders foot, then repetitive injury can occur

Sesamoiditis

This was the case with Lisa. She had been happily riding in the same version of a particular cycling shoe for years, and a change in shoe brought about symptoms of sesamoiditis.

Evaluation of her new shoe revealed that the cleat was positioned too medial (toward the midline). Note the difference between her old shoe (on the left), and her new shoe (on the right).

I also discovered that the shape of her new cycling shoe was curve-lasted, whereas the shape of her old cycling shoe was straight-lasted. (And the straight-lasted design was far more compatible with her foot shape.)

This combination of medial cleat placement and change in shoe last from straight to curved contributed to her painful symptoms of sesamoiditis.

If you are a cyclist who has recently experienced injury, it would be beneficial for you to evaluate your cycling shoes and cleat placement. This is especially true if new symptoms arise soon after wearing new cycling shoes, or after increasing your training frequency, duration, or intensity.

Sesamoiditis can be a challenging problem to resolve, so it’s important to seek immediate medical attention at the first sign of injury or symptoms.

The physicians and surgeons at San Francisco’s Financial District Foot & Ankle Center are experts in treating sesamoiditis, and in treating lower extremity cycling injuries in general. If you have cycling pain, give us a call today at (415) 956-2884.

Spin Class and Forefoot (Sesamoid) Pain

Reader Mary makes a good point of caution:

“I love spin cycling and wore mountain bike cycling shoes in class. I fractured my right sesamoid bone in my foot. I did not clip in–just used the cages. I haven’t been able to go back to spin cycling since the injury.”

Sesamoiditis is a common condition where one of the two bones underneath the big toe become inflamed, injured or fractured. This most commonly occurs when there is repeated, constant pressure or force applied to the sesamoids or during a one-time time traumatic event.

This image shows the anatomy of the sesamoids as they relate to the big toe joint.

Sesamoiditis

I have treated many cases of sesamoiditis and fracture that happened during spin classes. Typically, this happens when the pedal rests squarely below the forefoot or when the majority of the class is spent out of the saddle.

You may need an MRI to confirm that the fracture is healed before going back, and you will definitely need to modify your cycling form. Less standing and less resistance when you do stand will give your quads more of a workout, and will also reduce the force going through the sesamoids.

Cycling Shoes and Bunions

Clipless cycling shoes are notoriously tight. This is great for fit, and not so great if you have a wide forefoot or bunions. If you are a cyclist and suffer from bunions or have a wide forefoot, the following shoe-fitting recommendations should help.

Cycling_Bunion

  1. If possible, try and find shoes that don’t have a strap that tightens over the bump as seen above. Ideally, you will want to wear shoes that have either 3 straps or an offset strap away from the bump as this image shows.

Cycling_3_Straps

  1. If you already have a shoe that secures and tightens directly over the bump, simply undo the strap and avoid using it entirely as the following image shows.

Non-Slip Work Shoes for Narrow Feet

If you need a non-slip shoe for restaurant or housekeeping work and you have a narrow foot, your choices are very limited. Fortunately, Skechers makes a non-slip lace shoe for men that — even though sized medium — runs narrow. The style is called Rockland-Systemic and can be purchased from Zappos.com.

First and foremost, this shoe is great because it laces (as opposed to being a slip-on style), which is always better for the narrow foot. Also terrific is the fact that there are 6 sets of eyelets: the more eyelets there are, the better the shoe fit, especially for a narrow foot.

Finally, there is no hourglass in the waist of the shoe, which provides support in the arch where needed most. This also makes for a stable foundation if orthotics are to be worn inside the shoe.

Hiking Boots & Bunions

Hiking boots are designed to resist side-to-side motion. This is typically accomplished by using a stiff upper and reinforcing the shoe both laterally and medially. Although this is great for support, it can make the shoe feel like a vice grip for those hikers having bunions or needing extra forefoot width. If you have bunions, then you will want to make sure your shoe doesn’t have additional trim over the bony prominence.

If it does, then removing the trim can mean the difference between comfort and pain. The following image is a hiker having a Tailor’s bunion. As the image above shows, it was easy to remove the trim, making the boot more forgiving in those otherwise tight areas.

You can also modify the lacing as the last tutorial in the following video shows.
