So, i was wondering that can you walk in ESO, is there a possibility to do that. I didn't figure it out in the last beta.

Yes, you can map a keybinding to "toggle run/walk." It is rather slow when walking on foot, but on horseback it is a nice pace when setting out on a long journey.

Thank you

Yes, you can walk! It's not for everyone, but I walked everywhere in Skyrim, and I didn't use fast travel. It's amazing how many details escape you when you fly by on horse that you see when walking. However, due to the short length of the weekend beta, I used the running horse and wayshrines because I wanted to get to level 10 to try Cyrodiil before it ended. At launch, however, I plan to take a slower pace walking and see what I can see.
