Inclusion criteria
Inclusion criteria: 1. Group 1 - Men and women aged =20 years. - Individuals who have experienced discomfort or functional limitations in foot function and mobility since the onset/diagnosis of diabetes. - Able to complete the survey in person or remotely (online). 2. Group 2 - Healthy men aged 20–30 years. - No history or evidence of neuromuscular disorders affecting the foot, lower extremity, or other body regions. - Medically able to participate in approximately 2 hours of low-intensity physical testing (e.g., walking and balance tasks) without health-related concerns. 3. Group 3 - Male participants aged 50 to 70 years. - Individuals with a clinical history of Diabetes Mellitus who currently have no foot complications, such as ulcers, infections, or open wounds. - Participants must have a Linear Foot Length of 265 ± 5 mm or habitually wear a shoe size of 265–270 mm. * Definition: Linear Foot Length is defined as the straight-line distance from the posterior-most point of the heel to the tip of the longest toe. - Individuals capable of continuous gait on a treadmill. (The protocol involves approximately 60 minutes of total walking: 6 sessions × 10 minutes each). - Participants must have no underlying health issues that would prevent them from participating in approximately 2 hours of low-intensity exercise (e.g., static standing, walking). - Upon selection, the individual must be able to strictly adhere to the predetermined experimental schedule.
Exclusion criteria
Exclusion criteria: * Common to All Groups - Direct affiliation with the research team: Students currently supervised by the Principal Investigator (PI) or researchers affiliated with the same laboratory/department. - Foot-related complications or deformities: Individuals with active foot wounds, ulcers, or structural deformities that cause difficulty in wearing standardized footwear. - Mobility impairment or health vulnerability: Health-vulnerable individuals who have difficulty walking or are unable to perform continuous gait on a treadmill. - Researcher’s discretion: Any other individuals deemed unsuitable for participation by the researcher for safety or study integrity reasons.
