Effect of toe box size on basketball-specific movement performance.
Article in Frontiers in bioengineering and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: While an expanded toe box (TB) design offers notable benefits for foot health in basketball players, its impact on movement performance remains insufficiently elucidated. This study aimed to explore this relationship and inform the development of advanced shoe designs. Methods: We conducted a controlled laboratory study with a within-subject crossover design. Thirty basketball players (25 males, five females; aged 18-20 years) performed standardized 5-m sprints, 180° lateral shuffling, and 45° sidestep cutting in six shoe versions. These versions systematically altered the toe allowance dividing line (TADL) (0, 1.5, 3 mm) and the sole center line (SCL) rotation (0°, 2°). Movement time, ground reaction forces, propulsion impulse, and joint kinematics were measured using optical timing systems, force platforms, and motion capture. Results: A 3-mm TADL extension significantly improved performance, reducing sprint, lateral shuffling, and sidestep cutting times by 6.53% (P < 0.01), 3.49% (P < 0.01), and 7.69% (P < 0.01), respectively, and increased propulsion impulse by 27.27% (P < 0.01). A 1.5-mm TADL extension improved sprint time by 4.02% (P < 0.05), though the effects on other movements were limited. A 2° SCL rotation showed no significant performance improvements (P > 0.05). Conclusion: Our findings suggest that shoes with enlarged TB improve both forward and lateral movements. Inward TADL extension optimizes performance by enhancing foot mobility and force transmission, while SCL rotation offers minimal benefits. These findings challenge the conventional tight-fitting shoe designs and provide insights for designing footwear that enhances agility and reduces injury risks.
