What about using str_to_date() to create a date from your format?

EDIT after reading your comment, I created a table like yours:

mysql> SELECT fid, fdate FROM test;
+------+------------+
| fid  | fdate      |
+------+------------+
|    1 | 10/9/2010  | 
|    2 | 17/9/2010  | 
|    3 | 19/09/2010 | 
+------+------------+

and then did

mysql> SELECT fid FROM test WHERE STR_TO_DATE(fdate, '%d/%m/%Y') <= DATE_ADD(NOW(), INTERVAL 10 DAY);
+------+
| fid  |
+------+
|    1 | 
|    2 | 
+------+

Seems to work. What exactly do you get?
