The most common complaint at tango social dances (known as Milongas) is the quality of the floor. It might be too sticky, too shiny, too rough, too slippery, too hard, a bit uneven, the wrong colour... the list goes on. So if people are that sensitive to the detail of the floor, how is it possible to dance in a field or on tarmac? Surely that would be even worse!!!
It is definitely true that some things are easier on a good floor compared to a rough one. You can pivot easier, you can slide better, and barridas are far less challenging on a good smooth floor than they are on a rough one. But with a few adaptations you can dance almost as easily on flat grass as you can on polished oak
And the first thing to look at is your choice of footwear... or more specifically the choice of sole.
Different sole materials behave very differently depending on where you are dancing. Some might work perfectly in one place but not be great in another. and some materials will work better for leaders than followers, or vice versa. A lot of this will be down to your style of dancing and the only way to find out is to try them, but here are a few suggestions to start from...
The design of the shoe is something you should pay attention to as well as some work a lot better than others.
Start with these ideas and see what works for you. But as always remember safety and bend your knees.
