I'm the opposite: I wear long pants, shoes, and socks year round, only my upper garments change for the seasons (T-shirts in the summer, long sleeves in the spring/fall, hoodies/jackets in the winter).
90°F outside? I'm in jeans. Going to the beach? Socks and sneakers, baby (though I'll wear bathing trunks). Even when I was a mail carrier walking literally 10 miles a day in 90% humidity, I was wearing long pants. My coworkers/customers thought I was crazy, and maybe I am, but that's just how it be.
