#### 4.1.3 Qualitative Feedback  
The axial coding procedure within inductive thematic analysis revealed three main themes: _Aesthetic Design, Technical Properties_, and _Usability and Comfort_. Each theme includes both positive and negative perspectives and reflects participant feedback in four Orthotic Categories and three Design Types. Overall, perceptions of all four Orthotic Categories vary strongly concerning design, technical aspects, usability, and comfort. In general, the Orthotic Categories of _Short-Leg Orthoses_ and _High-Leg Orthoses_ are often associated with serious injuries. _Short-Leg Orthoses_ focus on \"stabilization\" (P83, P56) and \"facilitates mobility for users with lower leg injuries\" (P110) but offer limited practicality in daily life. _High-Leg Orthoses_ offer \"robust protection for serious injuries\" (P27, P101, P110), but are \"bulky\" (P5, P24, P26, P81, P163), \"heavy\" (P7, P22, P32, P119) and \"restrictive\" (P39, P83, P113), so their design \"looks like a \begin{table}

Table 2: Post hoc pairwise comparisons within orthotic categories and design types for Likert scores of device acceptance and design expectations. Significance codes: * (\(p<0.05\)), ** (\(p<0.01\)), *** (\(p<0.001\)), *** (\(p<0.001\)), *** (\(p<0.0001\)), ns = not significant. Figure 6: This figure contains two boxplot diagrams, including the rated device acceptance (**a**) and aesthetic design expectation (**b**) for the three Design Types in each Orthotic Category. The x-axis lists the four categories: _Short-Leg Orthoses_, _High-Leg Orthoses_, _Foot Bandages/Textiles_, and _Foot Drop Orthoses_. The y-axis represents the corresponding scores from the Likert rating. The boxplots are color-coded to distinguish the design types: _Generative AI_ in red, _Orthopedic products_ in yellow, and _Development concepts_ in blue. Asterisks indicate significance levels: * (\(p<0.05\)), ** (\(p<0.01\)), *** (\(p<0.001\)), *** (\(p<0.0001\)), *** (\(p<0.0001\)). ski boot\" (P144). Participants mentioned that these designs \"could not be worn with regular shoes\" (P75), \"leading to clothing restrictions\" (P101). In contrast, _Foot Bandages/Textiles_ are perceived as \"sporty\" (P26, P39), \"modern\" (P34, P156), and \"simple\" (P56, P84) because of their \"unobtrusive design\" (P8) and \"can be worn with shoes\" (P13, P46), but they are also viewed as less suitable for serious injuries. Lastly, _Foot Drop Orthoses_ have a \"functional design\" (P161) which is \"not conspicuous\" (P56, P84, P163) and directly addresses medical needs but is also seen as \"too mechanical\" (P8, P156), \"not stable\" (P21, P53, P73), and \"old-fashioned\" (P13, P22).
