1) It is mentioned in the daf the issue of Eiruv Techumin for the entire year, with a condition (for the east or for the west, or none). My question is, can a person do eiruv for the entire year for one direction only, no condition. I mean, that he put his eiruv 2000 from his city, in a safe place, food that will not spoil, and for the entire year he will be able to walk to that direction 4000 amot. is there an "expiration time" for the eiruv?
2) Also, can a man do eiruv with his feet, and say that this eiruv is for the entire year?

1) Sorry for taking so long to reply to your question. The answer to your first question seems to be no - there is no expiration date for an Eiruv. As long as the food hasn't spoiled and the person hasn't changed his mind, the Eiruv remains remains in effect. There is no reason to believe that the Gemara there (Eiruvin 37b) is putting an upper limit on the length of time that one can make an Eiruv. The focus of the Gemara is on the ability of the person to make a Tenai based on Bereirah. In fact, perhaps the phrase "l'Shabasos Shel Kol ha'Shanah" could be interpreted to mean all the weeks of THE year (instead of all the weeks of THIS year). Meaning, he is not putting a one year limit on his Eiruv.
2) The answer to your second question is directly addressed in the Shulchan Aruch. In Siman 416, Se'eif 2, the Mechaber says that if one made an Eiruv with his feet for the first day of Yom Tov, he needs to remake it for the second day of Yom Tov; this is true even if he intends the Eiruv to remain in effect for both days (Mishnah Berurah). The only time it will work for more than one day is for the two days of Rosh haShanah because these two are considered like one long day (Mishnah Berurah).
