Post Injury Running Shoe Recommendations
for the Return to Participation
for Sports Medicine Professionals

By: Bruce R. Wilk, PT, OCS & Anthony R. Di Mercuri

Following a running-related injury, patients often seek guidance from a sports medicine professional on proper shoe selection. It is vital for a sports medicine professional to be able to identify and evaluate patient need, offer recommendations, and isolate defective or worn out shoes. A safe and proper return to participation begins with a worthy pair of running shoes and a healthy training program. Choosing a shoe free from defects and based on individual gait analysis has aided injured patients in a faster return to safe running. (1)


Gait Analysis in Shoe Selection

When purchasing the ideal running shoe, patients should begin by consulting with a specialty running shoe store. Most specialty running shoe stores routinely use video gait analysis, on a treadmill, to provide baseline information about an individual’s specific needs before recommending any running shoes. Video gait analysis is an effective way to observe and analyze individual foot biomechanics during .video gait analysis, as an evaluation of full gait is required to adequately analyze the patient’s foot and gait pattern.(2)(Figure. 1) Minimalist shoes and racing flats should be used for the initial video gait analysis so the shoe doesn’t affect any gait mechanics, such as pronation.(2,3) It is not safe for patients to run barefoot on a treadmill; thus, barefoot running should never be used for any video gait analysis. Before taking the patient on the treadmill, make sure all metatarsals of the foot are sitting evenly on the platform of the shoe, taking notice of the width of foot. Any portion of the foot sagging over the edges is signal to an improper fit and can lead to an inaccurate analysis, as well as, discomfort. During video gait analysis, look for non- neutral gait patterns, and listen to the sound of the foot strike. Once video-taped, analyze the gait pattern in both slow motion and full speed to precisely evaluate any signs of over pronation or supination. Evidence of over pronation or supination, proven by video gait analysis, can help the patient select a shoe that works with their gait pattern.

With a significant amount of over pronation, the patient will benefit from a more stable, supportive shoe, classified in the stability category. Limiting the amount of movement in the rearfoot, allows the patient to have maximum support upon foot strike. A study presenting rearfoot motion with neutral shoes versus stability/motion control shoes proved that a runner in a neutral shoe had a 6.5° movement while the stability/motion control was insignificantly less. (4) These shoes come equipped with medial posting and firmer materials built into the shoe to help prevent the over pronation during foot strikes. A patient who supinates will benefit from a less stable, more cushioned shoe, providing more impact resistant materials such as gel and air. The salesman at the specialty running shoe store should not only know how to properly analyze gait but must be knowledgeable about a variety of different shoes in a variety of brands. The salesman should attempt to fit as many shoes on as possible, keeping within the category recommended for the patient. Once a few shoes have been narrowed down, the patient should try on the different shoes and focus on the comfort and fit of the shoe. Specifically, observe how the shoe moves when striking the ground, how the rubber compresses on the foot, and the patient’s overall subjective comfort level. With the new shoe, have the patient run again on the treadmill, and analyze the gait mechanics during initial contact, midstance, and push off. Check if the shoe is digging or rubbing on any portion of the foot. A patient running with too much support will present a clucking sound upon foot strike; whereas, a patient running with too little support will present a slapping sound upon foot strike. Most importantly, ask the patient if the shoe feels like it is a part of the foot. A well fit shoe will feel like a continuation of the foot.

Runners, historically, have used more supportive shoes early in training and progressed towards less shoe (lighter weight, less platform) later in training. This traditional concept of running may work for seasoned athletes, but for injury management, always go with more shoe, as more support is necessary for safe, initial return to participation. Upon return to participation, the patient’s feet are reintroduced to body weight load. Sudden body load increase can stress healing muscles and bones. Load stress brought on by over pronation is increased up to 200%, thus the control of initial pronation (support shoes) is much more important in running shoe design than cushioned shock absorption.(5) Therefore, if a patient is nursing an injury and making an attempt to return to athletics, then more load support will likely increase safe injury management.

Detecting Defective Running Shoes

Avoiding defective running shoes is critical to preventing further injury. An athletic shoe should be constructed so its upper, midsole and outer sole is firmly attached. (Figure. 2) Inflexible shoes can cause calf muscles to over work and can contribute to the development of specific injuries. (6) Before recommending a shoe, check the construction of the shoe. The shoe should continuously be glued together correctly at all locations. The upper (mesh portion) should be glued straight into the sole. The sole of the shoe should be level to the surface with which it is resting.(8) Check for asymmetry from side to side, on each shoe. If the shoe is able to be rocked, then it may not adequately support the foot from rolling excessively when worn. When using a shoe with air pockets or gel pockets, check to see if those materials are still inflated. Sometimes, the support technologies, within the shoe, tend to deflate, thus leaving the shoe purposeless. A shoe should have flexibility, with the flex occurring specifically at the metatarsal heads, widest portion of the shoe (toe box). Furthermore, when choosing a running specialty store, be sure that the shoe selection is always current. An older model shoe that has been discounted may not be the best choice because some materials within the shoe, such as gels and rubbers, do have a limited shelf life.

A safe return to running activities should initially begin with some fitness walking with full heel to toe motion and then progress to gliding, which is flat foot initial contact for long, slow distance. The shoe should allow an individual to move through a full gait heel to toe motion. A forefoot gait pattern is practiced and refined later with accelerations during training and plyometric exercises. Sports medical professionals should consider the extent of the injury, kind of injury, and training level of each individual before recommending a return to training program. Refining performance should focus on biomechanical energy efficiency. This applies to a precisely fitted shoe. Foot strike energy should be returned at the right location at the right time and a reduction of energy is more important than return of energy. (9) Reducing the amount of energy upon foot strike for a patient returning to participation thus allows the patient to safely return to activity progressively through the correct fitness regime.
As a sports medical professional, presenting ample knowledge on shoe recommendations can greatly improve the outcomes of injury management regimes. Provided with accurate information, a patient suffering from a running related injury can successfully and safely return to running.
