“…Our results may be counterintuitive in view of the literature on the testing of flexible shoes. Burns and Kram [12] compared two extreme shoe types -highly flexible running shoes and carbon-soled cycling shoes-and showed that the flexible shoe decreases 100-m sprint performance in men. However, it seems problematic to conclude that the stiffness of these shoe is the only factor responsible for improving performance, since both conditions proposed different pedal linkage.…”

Background: The aim of this study was to test the effects of cycling shoe outsole stiffness on both performance and comfort parameters during sub- and supra-maximal cycling tests. Methods: Two groups of recreational women tested three cycling shoe conditions with differing outsole stiffness. One group of 8 women performed four cycling tests of 3 min composed of two intensities (100 and 140 W) and two pedaling rates (70 and 100 rpm) for each pair of shoes. Metabolic and subjective perception of comfort measurement was evaluated with each shoe. Another group of 12 women performed 6-s all-out sprints against two external resistances (0.4 and 0.7 N/kg) to determine force-velocity relationships with the three cycling shoe conditions. Results: The main findings are that the stiffness of the investigated outsole cycling shoes (i) does not influence cycling performance whatever the test (ii) while the perception of comfort is largely degraded compared to the most flexible shoe. Conclusion: Maximizing stiffness should no longer be of the highest design principal for beginners or recreational women cyclists.

“…On the one hand, the studies that tested large differences in shoe stiffness had to use running shoes for the minimum stiffness condition [e.g. 6,[11][12][13][14][15][16]. But the running shoe inevitably requires the use of flat or toe-clip pedals, while the cycling shoes used to qualify stiffness require clipless pedals.…”

“…Quantifying acceleration and top speed each require short-duration, high-intensity trials. Therefore, with enough recovery time in-between, they can be repeated at the same intensity without decreases in performance outcomes [ 52 ]. Running economy experiments involve longer duration trials (usually 5 min) at a sustainable, aerobic, steady-state intensity.…”

The recent and rapid developments in track spike innovation have been followed by a wave of record-breaking times and top performances. This has led many to question what role “super spikes” play in improving running performance. To date, the specific contributions of new innovations in footwear, including lightweight, resilient, and compliant midsole foam, altered geometry, and increased longitudinal bending stiffness, to track running performance are unknown. Based on current literature, we speculate about what advantages these features provide. Importantly, the effects of super spikes will vary based on several factors including the event (e.g., 100 m vs. 10,000 m) and the characteristics of the athlete wearing them. Further confounding our understanding of super spikes is the difficulty of testing them. Unlike marathon shoes, testing track spikes comes with a unique challenge of quantifying the metabolic energy demands of middle-distance running events, which are partly anaerobic. Quantifying the exact benefits from super spikes is difficult and we may need to rely on comparison of track performances pre- and post- the introduction of super spikes.
