Reducing the risk of injury by more than half sounds like hard work, a lot of training, and – if we’re being honest – almost utopian. Achieving this by simply choosing the right running shoes seems far too simple at first glance. Yet the results of the Run Better Research Study show just that. Specifically, our running shoes, or, more precisely, the midsole technology we run with, influence the risk of developing running injuries. By up to 50% – particularly at the knee and Achilles tendon. Impressive findings on where we get injured, why we get injured – and what we can change. An overview.
Running injuries are still a nagging issue that runners have to deal with far too often, even today. We have to cancel planned runs, skip training. Because if we are injured, we simply have to take a break from running. The reason for running injuries is mainly overload or fatigue of our tissues, so-called overuse injuries (Chapter 4, Part 1: It’s All a Question of (Too Much) Stress: Why We Get Injured While Running).
The recently conducted Run Better Research Study shows that too many runners still suffer from running injuries. Of the nearly 1,700 participants in the study, 52.96% got injured at least once within a year. Runners were considered injured if they had to miss at least one running session due to pain or discomfort. This applied to more than one in two.

But what are actually the reasons why we get injured?
To find out, the participants filled out a questionnaire looking back on their running behavior over the past twelve months. The data collected were age, gender, height, and body weight. With regard to their running behavior, the participants also indicated the running sessions they had completed per week, the distance they had run per week, their running experience in years, and the running shoes they had worn. The German running magazine “LÄUFT” evaluated the data by assigning the above-mentioned running shoe models to the four different sole technologies neutral, rocker, support, and U-TECH™ from True Motion.
The study participants had to meet certain minimum requirements. All 1,700 runners had to have run at least once a week, with a total distance of at least ten kilometers per week. A running shoe with the same sole technology had to be worn in more than 75% of the running sessions.
The result of the evaluation: in all running injuries recorded, only the running shoe worn, i.e., the midsole technology used in it, had a significant influence on the risk of injury. Significant means that the result is so unambiguous that it cannot have been obtained by chance. Furthermore, the study shows that in the case of knee injuries, running experience also had a minimally significant influence in addition to sole technology. The same is true for gender with regard to Achilles tendon injuries.
Table 2 shows the 1,000-km incidence for the five running shoe technologies. The incidence indicates the relative frequency of an injury according to different running shoe technologies in relation to a running distance of 1,000 kilometers. The data are nominalized to the incidence for U-TECH™ Technology (1.00). Values greater than 1.00 thus indicate an increased risk.

The data are nominalized to the incidence for U-TECH™ Technology (1.00). Values greater than 1.00 thus indicate an increased risk.
But in order to compare running injury risks between different shoe technologies, we need a measure that shows the influence of running shoe technology independent of running experience. For this purpose, the injury frequencies of all participants were extrapolated to an assumed running distance of 1,000 kilometers. The so-called 1,000-kilometer incidence shows that the probability of an injury was greatest in shoes with a midsole rocker. In contrast, runners who ran in running shoes with U-TECH™ technology were least likely to be injured. The risk of injury across all body regions is 25% higher in rocker shoes than in biomechanical U-TECH™ running shoes (see Table 2). The risk is 22% higher in neutral shoes compared to U-TECH™, and 16% higher in support shoes.
Running injuries include a whole range of overuse injuries. When running, forces act primarily on our lower extremities with every step we take. In addition to the knee, Achilles tendon, calf, shin, and hip, the back also frequently hurts. But which part of the body is particularly susceptible to injury when running?
Across all sole technologies, the study participants got injured primarily at the knee: 26.18% of the injuries occurred at the most complex joint of the human body. The Achilles tendon was the second most frequently affected at 13.82%. This was followed by back injuries (12.47%) and shin injuries (3.39%). In all other regions, no statistical difference across sole technologies could be found.
In the case of knee injuries, another parameter was identified as an influencing factor in addition to sole technology. Runners with less than three years of running experience injured their knees more frequently. With regard to the different sole technologies, the injury rate was highest when runners ran in neutral shoes (27.78%) or neutral shoes (25.42%). The injury frequency in running shoes with U-TECH™ was less than a half of this rate (see Table 3).
In addition to sole technology, differences in injury frequency can also be related to the participants’ gender: For example, men were significantly more likely to get injured at the Achilles tendon than women. Across genders, the risk of injury to the Achilles tendon was lowest in running shoes with U-TECH™ and support. Taking into account that most participants ran in neutral shoes (60%), U-TECH™ can decrease the risk of Achilles tendon injuries dramatically. The greatest risk of injury to the Achilles tendon was in neutral shoes (15.47%).
Table 3 shows the distribution of injury frequencies (relative risk of a running injury). The data are to be understood as % of all subjects.

Furthermore, when we run, we not only put stress on our lower extremities, but also on our backs. Overloads and incorrect loads as well as fatigue fractures can also lead to injuries here in the sense of overuse injuries, which prevent us from running. At 13.5%, the risk of injury was highest in neutral running shoes. Runners who ran with U-TECH™ complained a lot less about back problems.
Many runners are also familiar with injuries of the shin, including so-called shin splints. No wonder they are considered typical running injuries. Although the shin was the least frequently injured structure in the comparison of body regions, the risk of injury was also lowest here with U-TECH™ (0.71%) and most pronounced with neutral shoes (4.24%).
To summarize: Runners are most frequently injured at the knee. The risk of injury was highest in neutral and stability shoes with support technologies. In relation to all other body regions, running in neutral shoes made them most susceptible to injury. U-TECH™ technology, on the other hand, can be identified across the board as the lowest-risk sole technology in terms of running injuries. This is true for running injuries overall, but also individually for injuries to the different body regions.
But why is that?
True Motion’s U-TECH™ technology has been inspired by human structures in form and function – such as the menisci in the knee or the fat pad around the heels. Based on this, U-TECH™ technology is a U-shaped midsole in the rearfoot. This design allows the heel to sink into the designated recess during transition. In this way, the forces that occur during running are centered and aligned through our body – as nature intended. Potentially damaging rotational forces in the knee are rendered harmless and a significant factor in the development of knee injuries is eliminated. Or to put it another way: U-TECH™ allows us to move naturally.
The results of the Run Better Research Study show that this technology works regardless of whether we are supinating, pronating, or a neutral runner. There is no need to differentiate between runner types. And that is also logical. Because U-TECH™ harmonizes with the individual movement dynamics of all runners instead of interfering with them.
That’s why the running shoe models with U-TECH™ don’t differ according to runner or gait type – but according to the intended usage. Depending on whether your next run should be as comfortable and cushioned as possible, a little faster, or off-road, different running shoe models are a particularly good fit (Find the right True Motion running shoe with our shoe finder).
