Translation of sneaker in Spanish

Do you speak German? How many languages can you really speak? I know Russian, English, Italian and some Spanish. I want to learn more Spanish, let's try to do it together? I love this forum.
Sorry if I did not write back, I was in Napoli during the holidays, then back at work, once again I have so much to do at the weekend, but I will do my best. Greetings from Italy. Marco.
I teach at the university of natural sciences. I have studied at the ETH in Zurich. At that time I started learning Spanish and I found Vocabulix. Since then I'm using it regularly with joy.
