Well, I don't recommend trying it on a wet tile floor and cheap yoga mats can be super-slippery. Good equipment is essential in this equation in order to provide enough friction to keep from slipping. However, just like I can walk across a slippery floor without falling by placing my weight correctly on my feet or I can completely wipe out by not taking care, there is a sweet spot in down-dog that will make the difference between sliding and not sliding.
