It is impossible for me to resist any question that suggests the possibility of poisonous reptiles. And Nicaragua has them. Coral snakes! Rattlesnakes! Even the lovely fer-de-lance!
Cabela’s Kangaroo Featherlight boots

Of course, there聮s no reason to be alarmist. Snakes, even venomous ones, are like most other creatures on this earth: They hear (or in the snakes聮 case, feel聴they don聮t have ears) you coming, and want to get out of the way. Which is all to the good.
Anyway, basic snake safety starts with leather or other thick-skinned boots that go as high as possible, as the area around your ankle is most vulnerable. I聮d give serious consideration to tall hunting-style boots, such as Cabela聮s Kangaroo Featherlight boots ($144; www.cabelas.com). They聮re not insulated and do not have a waterproof liner, which makes them a little cooler. And they put leather protection well over your ankles.
In a more traditional hiking boot, Asolo聮s TPS 535 V ($180; www.asolo.com) would be fine, as would the Vasque Wasatch GTX boots ($160; www.vasque.com).
You also can reinforce any pair of boots with several snake-resistant add-ons. Rattlers Knee-Hi Snakeproof Gaiters ($48; www.rattlersbrand.com), for instance, strap onto any good boot and give you bite-proof protection up to your knees. You also can buy full chaps, which extend above the knee. TurtleSkin Snake Armor Chaps ($225; www.turtleskin.com) are a good example.
Good luck!
