Roya Emamgholizadeh Minaei, Mohammad Hajaghazadeh, Teimour Allahyari, Hamidreza Khalkhali, Mansoor Keramat,
Volume 4, Issue 1 (6-2016)
Abstract

Introduction: Foot anthropometric dimensions could be useful in designing comfortable footwear. The objective of this study was the measurement of foot anthropometric dimensions in a group of students.

Methods: This was a descriptive study in which 21 dimensions of foot for 580 males and females were measured manually. To measure the foot dimensions, a digital caliper and a tape were used. The measured dimensions included the important lengths, widths, heights and girths of foot. Descriptive statistics such as percentiles, mean and standard deviation were calculated for the collected data. To test and survey of the mean of foot dimensions between males and females, statistics such as independent t-test and effect size (Cohen’s d) were used.

Results: The values of mean, standard deviation, the 5th, 50th, and 95th percentiles were calculate and tabulated for the total studied population and for gender. In all measured foot dimensions, males had bigger dimensions than females. Gender had different impacts on the measured foot dimensions. The mean of all foot dimensions was significantly different between males and females (P value = 0.001). Digital pattering of I and II were observed in 78% and 22% of the studied population, respectively.

Conclusions: In the present study, important anthropometric data of foot were collected for a group of students. The presented percentiles could be used in design of male and female shoes. Conducting similar studies in children with different age categories could help completion of the anthropometric database.

Abstract
Introduction: The aim of this study was to evaluate the effect of unstable shoes on lower limb kinetic parameters of walking in healthy male students with different geometric shapes. Today, various shoes have been developed to reduce the effects of injury parameters and improve performance parameters for walking.
 
Methods: 20 of the healthy male lambs were selected 178.96 ± 3.92 cm, 27 ± 3 years old, 73.99 ± 6.6 kg and 42 (EU) number, in four position, domestic production unstable shoes , foreign Similar unstable shoes, regular control shoes, and barefoot, The Kinetic parameters associated with Lower limbs was evaluated by force plate while walking. To examine the significant statistical differences between dependent variables between the four conditions of foot cover, the general linear model and the analysis of variance with repeated data and / or Friedman in the case of normalization of data in the alpha level of 5% using software version 23 SPSS was used.
 
Results: In relation to the kenetic parameters of the lower extremity, there was no change in the peak Postereior Force and the peak active force in the case when there was a significant change in the peak passive force and  peak anterior Force and and the free movment and loading rate.
 
Conculosion: The results indicate to the domestic production unstable shoes inefficiency  in reducing the damage and increasing the comfort of the lower limbs.
The Impact of Occupational Categories on Foot Pain and Functional Performance: A Cross-Sectional Study Using the Foot Function Index (FFI)
Samin Asghari Eskoui, Mahmood Reza Azghani, Sadra Jalali,
Volume 13, Issue 3 (9-2025)
Abstract
Objectives: Musculoskeletal disorders (MSDs), particularly foot problems, are among the leading causes of reduced quality of life and work productivity. Evidence suggests that occupational conditions and daily activities play a crucial role in the development of foot pain. This study aimed to examine the relationship between occupational status, severity of foot pain, and functional impairment in various occupational groups using the Foot Function Index (FFI).
Methods: This cross-sectional study included 2,848 participants from East Azerbaijan Province, Iran. Based on occupational status, participants were categorized as employees, self-employed, housewives (only women), and students. Data were collected using the FFI questionnaire. The data's normality was tested using the Kolmogorov–Smirnov and Shapiro–Wilk tests. Since the distribution was non-normal, inter-group comparisons were performed using the non-parametric Kruskal–Wallis test, followed by pairwise comparisons with the Mann–Whitney U test and the Bonferroni correction, as necessary.
Results: The results revealed that students, both men and women, reported the highest levels of foot functional problems, while employees and self-employed individuals had lower FFI scores. Among women, housewives reported fewer problems than students. Statistical analyses confirmed significant differences among the occupational groups (P < 0.001).
Conclusion:  This study demonstrated that occupational status is directly associated with foot pain and functional impairment. The results highlight that students, as a high-risk group, require special attention in preventive programs and orthopedic and ergonomic interventions. Identifying the impact of occupational factors on foot health can provide a basis for designing strategies to improve occupational health and reduce the burden of MSDs. 

Barefoot Shoes and the Clinical Challenges of their Use in Iran: A Qualitative Study from the Perspective of Retailers
Shafe Abbasi, Roghaye Lotfi Esfahanjegh, Farideh Babakhani,
Volume 13, Issue 4 (1-2026)
Abstract
Objectives: Barefoot shoes are recognized as a product for managing musculoskeletal disorders, and prolonged use of inappropriate shoes can have negative health consequences. Despite the growing use of these shoes in Iran, there is limited evidence regarding the associated clinical and practical challenges. Examining the experiences of vendors can help identify barriers to the supply and use of this product, providing practical data to improve prescription practices, consumer education, and the quality of clinical care.
Methods: This qualitative, ergonomics-focused study examined the challenges and opportunities of using barefoot shoes in Iran from the vendors' perspective. Data were collected using a modified Anderson questionnaire, validated by three orthotics and prosthetics specialists, and completed by ten vendors. The thematic analysis of the data highlighted the needs and challenges related to barefoot shoes in the Iranian market.
Results: Athletes, individuals with normal weight, and those with forefoot deformities reported the highest satisfaction with barefoot shoes, whereas individuals with conditions, such as severe flat feet or back pain without custom insoles, faced challenges. Additionally, foot scanning and the design of personalized insoles play a crucial role in improving comfort and reducing foot pain.
Conclusion: Barefoot shoes can improve the function of foot muscles when designed and used ergonomically. However, individuals with back pain, high arches, heel spurs, corns, or various types of blisters should use them with caution because improper use may exacerbate pain and worsen clinical symptoms.

Design shoe Last for men with flat feet
Shayan Kafi, Nasser Koleini Mamaghani,
Volume 14, Issue 1 (3-2026)
Abstract
Background and Objectives: Flatfoot (Pes Planus) is a prevalent musculoskeletal condition that results in multi-joint pain, premature fatigue, and balance instability. Given that mass-produced footwear in Iran often lacks alignment with Iranian anatomical characteristics, this research aims to determine the appropriate dimensions and indices for designing customized shoe lasts for Iranian men with flat feet. This approach seeks to enhance biomechanical performance and prevent excessive pressure and impact on the feet.
Methods: This applied-developmental study was conducted using a descriptive-analytical methodology. Data were collected through four primary instruments: a questionnaire (n=26), expert interviews, observation and analysis of existing commercial products, and anthropometric measurement of 10 users across 10 specific parameters, including footprint characteristics. The primary goal was to establish standardized dimensions for shoe last design, addressing the current lack of localized industrial standards in the domestic market.
Results: Findings indicate that public awareness regarding flatfoot and its associated corrective products is low, and users are dissatisfied with existing market solutions. Clinical observations confirmed that most Iranian orthopedic centers focus primarily on insole production, with treatment centered on symptom control and pain reduction. Based on the urgent need for optimized products and the collected anthropometric data, a sole pattern and a 3D shoe last model were designed and developed.
Conclusion: The results highlight the importance of enhancing medial longitudinal arch support through specialized shoe last design, which can significantly mitigate complications associated with flatfoot. The final outcome —comprising the sole pattern and the customized shoe last— demonstrates that integrating anthropometric data into engineering design environments provides a robust platform for manufacturers, ultimately leading to improved consumer satisfaction and enhanced foot health.
