So, my wife and I go to Walt Disney World in Florida a few years ago. It was hot, and sweaty. My body loves fun. It will be involved with fun, wherever it is, but my body is whimpy when it comes to pain. My feet can't stand too much pain. And now, a little weather info.
Florida is a wonderful place to go, except the weather pattern is like the guy at the gas station giving you directions to some place he's never been. He just makes it up as he goes, and he knows if you don't know where you're going, you'll never find your way back to the station, and if you do, you'll end up buying a Slim Jim and a Monster drink - so Goober wins either way. Oh right, the weather in Florida.
We've been to Florida a few times; Once when everyone in the world, including Nostradamus wrote that it would me nice, and it was so hot, the Devil had to wear a hat. Another time, we packed short and tank tops, and it was 51 degrees. Okay? Weird weather. Anyway, one trip (the hot one) it was muggy. Not slightly humid. I mean muggy. It was so muggy, when you turned on the shower head, it said, "It's not even worth it".
So, my body is going to Disney. Yay! Woo Hoo, and then the mugginess began to visit my feet. Mugginess said, "Hey, I know you're size 13 and all, but you should expand - in width, cause it's muggy." That particular year, I bought Vans shoes. I love Vans shoes, however this particular pair had quite stiff sides, and my feet began to swell, and swell, and swell. My body began to protest, and then my mouth went into whine mode.
I tried everything from loosening laces to wearing flip flops, then the blisters began to appear. I remember the day that I waved the white flag to the Muggy weather, and spent $50 ($30 for the taxi and $20 for the new extra large shoes) to get relief.
Bottom line - Humidity makes you feet swell, and Shower heads can talk. That is all, for now.
