Bandy-legged is a term used to describe people or animals whose legs curve outward at the knees. The condition can cause discomfort, poor balance, and potential joint problems. Antonyms for bandy-legged include straight-legged, upright, and aligned legs. These terms describe legs that are straight, vertically positioned, and properly aligned with the rest of the body. Having straight legs is an advantage in terms of physical fitness and balance. Straight-legged individuals often have better posture, mobility, and stability. So, while "bandy-legged" might be used as an insult, there's nothing derogatory about having straight and perfectly aligned legs.
