Love this contrast too. I'm a guy who walk barefoot very often especially in spring, summer and early autumn in nature (forests, meadows etc. but I generally love nature and don't like cities BTW, especially big cities, in summer usually shirtless, in jeans only or with denim vest without t-shirt). I feel more fun when I'm barefoot side of a girl who wear shoes because shoes is symbol of femininty to me 😘, because girls are more delicate and need more protection for their feet but boy should not to afraid of contact with stones, sticks, cones etc. 😉 Barefoot walking make feet skin tough and rough so its more right for a boy and really unsexy for a girl in my opinion.
Girl who hiding her feet in shoes or/and socks side of barefoot guy is more mysterious and feminine, even in bedroom, during sleeping or sex for example in pair of nice socks. Supposedly female feet tend more to be cold so keeping socks on in bed increase girls arousal when she feel more warm and safety 🧐.
Even when I was train kick-boxing almost 20 years ago... I remember some girls in all groups (4 girls and about 10 guys in my group) and all the guys was train barefoot but all girls wore sneakers with socks during trainings.
