Volume 6, Issue 4 (3-2019)
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.
Evaluation of Usability and Discomfort of Safety Footwear in Different Industries of Mazandaran Province

Volume 10, Issue 2 (9-2022)
Abstract
Objectives: Providing safety for human resources in the industry is very important. Safety shoes are one of the most common PPEs that protect the foot against potential hazards. This study aimed to evaluate the discomfort and usability of safety shoes in different industries of Mazandaran province to find gaps in the quality of design and improve the design of safety shoes.
Methods: This was a cross-sectional study and was conducted in 2021.This study included employees of 11 different industrial companies that used seven safety shoe brands. They answered two researcher-made questionnaires, LPD (discomfort and general satisfaction) and SFUQ (usability). Data analysis was performed with Spearman rank correlation coefficient while Pearson correlation coefficient, and ANOVA test were also performed.
Results: In total, 226 men with a mean age of 36.33 ± 7.4 years were included in this study. The participants reported the lowest usability for the brand G (3.3 and 3.99), and the least discomfort and the most usability index with the brand A (1.2 and 5.35). Overall, the highest satisfaction was reported for brand A and the lowest satisfaction to brand G.
Conclusion: The findings of this study showed that the main problem in comfort and usability is probably related to shoe molds because the manufacturers of safety shoes import molds from abroad that do not fit the anthropometric characteristics of Iranian users’ feet.

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.
