Ok I'll try to translate it but forgive me if it's not 100% correct all the time. :
At 5:08 the the actual tickle talk starts. The host (in the middle) says that she can't concentrate because of all the giggling here (she is refering to the foot model (Reneta) on the right. She continues: "you might know that when s.o. tickles your feet and you're not exspecting it, it is (laughs) like a little torture" then she goes on that you can decide by yourself how much pressure you use to press your feet against the rolling massaging balls. It goes on at 6:16 when the other woman mentions that there is also a little radiator integrated and you can deactivate the massage-system and give your feet a little warm up. this is where the host reaches over to Renate saying this must be better for her just to warm up her feet and give them a rest.
It actually already starts at 4:18 where Renata starts laughing. Host (middle): What a giggling! Maybe Renata (hard to understand): It tickles. Host: Does it tickle? I think Renata just got to a reflex zone where she says, that's a ticklish one.
