On the other hand, designs from _OrthoticFootGPT_ were regarded as \"very aesthetic and modern\" (P41), \"sporty\" (P24), and featuring a \"nice design\" (P83), due to \"less conspicuous Velcro fasteners\" (P90) and a resemblance to \"winter boots\" (P159). In general, the _Sporty Design_ keyword led to designs perceived as modern and sporty, which were positively received by participants. The _ChatGPT_ outputs were described as a \"nice and modern design\" (P24) contributing to a \"self-confident appearance\" (P74). In comparison, _OrthoticFootGPT_ designs were associated with a \"sporty design\" (P9), resembling \"sport shoes\" (P74, P102, P138) and perceived as designs that \"remind one of a fashion brand\" (P89). It was also positively noted that \"the toes are not visible\" (P94). **Functionality:** The use of _No Keyword_ with _ChatGPT_ raised concerns about functionality, as the designs were perceived as \"not effective\" (P157) and \"not stable\" (P90, P150) due to the \"missing insole\" (P9, P14) and because they \"offer less protection (e.g., no padding)\" (P36). In contrast, the _OrthoticFootGPT_ designs \"offer good stability and fulfill [their] functional requirements effectively\" (P61) because they are \"easy to attach and remove\" (P89, P90, P152). For the keyword _Usability_, _ChatGPT_ designs were criticized for being \"too mechanical\" (P150) and \"complicated to use\" (P105, P111, P149). Meanwhile, _OrthoticFootGPT_ outputs were associated with \"simple handling\" (P36, P56), due to \"a good balance of stability and comfort\" (P36) and because \"it also gives the feeling that it has very useful functions\" (P21). In the context of _Social Acceptability_, _ChatGPT_ designs were described as \"too bulky, seems heavy\" (P14), \"unrealistic\" (P60), and \"impractical\" (P37), primarily due to \"too many straps\" (P9, P89) and \"components are mainly made of textile. Water...can be absorbed\" (P79). In contrast, _OrthoticFootGPT_ designs were perceived as \"very innovative\" (P93), featuring \"a good sole, similar to a shoe\" (P14), making them an \"eye-catcher for everyone\" (P21). Regarding _Sporty Design_, _ChatGPT_ was noted for its \"functional and rather simple design...suitable for a broad target group\" (P90). Similarly, _OrthoticFootGPT_ designs were defined as \"robust\" (P94), \"stable\" (P36, P105), and \"breathable\" (P33), with functionality that is \"easy to integrate for sports activities\" (P89). **Comfort and Fit:** The primary issues with _ChatGPT_ designs using _No Keyword_ were identified as being \"uncomfortable\" (P21) and \"impractical due to open toes\" (P37), concerns that were similarly reflected in the keywords _Usability_ and _Social Acceptability_.

In the context of _Social Acceptability_, designs generated by _OrthoticFootGPT_ were described as resembling a \"sport shoe\" (P21) or \"winter boots\" (P159), with positive feedback emphasizing that \"no toes are visible\" (P94). Regarding _Sporty Design_, a participant described the _ChatGPT_ output as follows: \"It looks like a boot. It does not attract attention and is therefore great for everyday wear. It makes you feel more confident\" (P74).
