Worth the Investment? Experts Weigh In on the Sense and Nonsense of Running Gadgets

Running is, in theory, one of the most accessible sports in the world. A pair of sneakers and a bit of motivation are typically all that stand between a person and the pavement. However, the modern market has transformed a simple activity into a high-tech arms race. From military-grade watches and fluorescent compression gear to specialized gels and carbon-plated footwear, the options are overwhelming.

The question for most runners is simple: which of these tools actually improve performance, and which are merely clever marketing? To identify the answer, a panel of experts—including sport scientist Bas van Hooren, sport physiotherapist Eline Peterse, physiotherapist Peter Eemers, and top athlete Anne Luijten—broke down the utility of common gear to determine what is truly worth the investment for running gadgets.

The Compression Sock Controversy: Science vs. Placebo

Compression socks are marketed as a way to increase blood flow and deliver more oxygen to the muscles, often carrying a price tag between 20 and 40 euros per pair. However, the scientific consensus is far from settled.

Bas van Hooren, a sport scientist, argues that the financial investment may not be justified. According to van Hooren, for every study suggesting that compression socks enhance performance, there is another that proves the opposite. He points to a specific physiological conflict: when muscles contract, the muscle fibers rotate to help the muscle work faster. Compression socks can hinder this natural rotation, effectively neutralizing any potential blood-flow benefits. In his view, the net effect is nearly zero.

Despite the lack of scientific backing, the “real world” experience differs. Eline Peterse, a sport physiotherapist, notes that many runners in her practice report significant relief from persistent calf or shin complaints after switching to compression socks. While she acknowledges that the effect has never been scientifically proven, she suggests that a placebo effect can still provide tangible relief for the athlete.

Regardless of whether the socks “work” biologically, the experts agree on a critical practical rule: never wear a brand-fresh pair of socks on race day. Van Hooren recalls a personal failure during a half-marathon where wearing unfamiliar, short ankle socks led to blisters, despite him finishing as the fastest Dutchman. The gold standard is to use trusted gear that is proven not to slip or cause friction.

Heart Rate Monitoring: Wrist Sensors vs. Chest Straps

Tracking pace and load is essential for progression, but the tools used to do so can provide conflicting data. The debate often centers on whether a smartwatch is sufficient or if a dedicated heart rate monitor is necessary.

Peter Eemers, a physiotherapist who works with elite athletes such as Abdi Nageeye and Sifan Hassan, suggests a shift in perspective. He often prefers training based on running speed rather than heart rate. The reasoning is that heart rate is volatile; it can be skewed by lack of sleep, caffeine intake, and other external stressors, making it an inconsistent metric for daily effort.

Conversely, top athlete Anne Luijten found heart rate data indispensable during preparations for major tournaments. Luijten notes that in specific conditions—such as extreme heat or hilly terrain—pace becomes an unreliable indicator of effort, making heart rate the more accurate gauge of intensity.

For those who rely on heart rate data, the hardware matters. Bas van Hooren warns against using the optical sensors on the wrist as a sole source of truth. Because of the constant arm movement during a run, wrist-based measurements are often inaccurate. For athletes engaging in heart-rate-led training, a chest strap is the only reliable option.

Managing Friction and Chafing

While less glamorous than smartwatches, friction management is a practical necessity for long-distance runners. Chafing is a frequent issue that can derail a race if left unaddressed.

The experts confirm that specialized tools like nipple plasters, sport tape, or anti-chafe products are effective solutions for preventing skin irritation. However, they also note that high-tech gadgets aren’t always the answer. In many cases, simply investing in a high-quality, well-fitting shirt can eliminate the demand for these additional products entirely.

the experts suggest that while gadgets can provide data and comfort, they should not replace an athlete’s ability to listen to their own body. Whether it is the choice between a chest strap or a smartwatch, or the decision to spend 40 euros on compression socks, the most valuable tool remains a deep understanding of one’s own physical limits and responses.
