I know of a couple of deserts, but a JUNGLE?  Oh, well, my problem is desserts, not deserts.  Fat man walks into a doctors office, doctor says, "You need to walk more, a lot more."  And I said, "But my feet hurt".  And he said, "That's because of your totally inadequate footwear.  Get some good shoes with support and your feet will feel better."  OK.  I did and sure enough he's right.  The clue to happy feet is good fit, and the W in the size of the shoe makes the difference.  I used to buy the cheap "crosstrainers" off the $20 shelf and then kick them off every chance I get.  Today I walked 2 miles before dawn and I am looking forward to more walking this afternoon, and I never get the urge to take them off. I like the price at Amazon, and I like the availability of the wide sizes.
