You don't have to make balance checks to walk across flat ground. There's a point at which the DM just says "Everyone automatically passes". Or for that matter, just ignores the fact that anyone might suggest requiring a balance check to walk across flat ground.
Of course, the minute the ground is at all uneven, and the DM decides there's a small chance of tripping, that tower shield and full plate guy is going *down*.

for example when they walk on narrow surfaces known as stairs. depending on how one reads balance.
BALANCE (DEX; ARMOR CHECK PENALTY)
Check: You can walk on a precarious surface. A successful check lets you move at half your speed along the surface for 1 round. A failure by 4 or less means you can’t move for 1 round. A failure by 5 or more means you fall. The difficulty varies with the surface, as follows:
Narrow Surface Balance DC[1]**** Difficult Surface Balance DC[1]
7–12 inches wide 10 **** Uneven flagstone 10[]2]
2–6 inches wide 15 **** Hewn stone floor 10[2]
Less than 2 inches wide 20 *** Sloped or angled floor 10[2]
1 Add modifiers from Narrow Surface Modifiers, below, as appropriate.
2 Only if running or charging. Failure by 4 or less means the character can’t run or charge, but may otherwise act normally.
Narrow Surface Modifiers
Surface DC Modifier[1]
Lightly obstructed +2
Severely obstructed +5
Lightly slippery +2
Severely slippery +5
Sloped or angled +2
[1] Add the appropriate modifier to the Balance DC of a narrow surface.
These modifiers stack.
Being Attacked while Balancing: You are considered flat-footed while balancing, since you can’t move to avoid a blow, and thus you lose your Dexterity bonus to AC (if any). If you have 5 or more ranks in Balance, you aren’t considered flat-footed while balancing. If you take damage while balancing, you must make another Balance check against the same DC to remain standing.
Accelerated Movement: You can try to walk across a precarious surface more quickly than normal. If you accept a –5 penalty, you can move your full speed as a move action. (Moving twice your speed in a round requires two Balance checks, one for each move action used.) You may also accept this penalty in order to charge across a precarious surface; charging requires one Balance check for each multiple of your speed (or fraction thereof ) that you charge.
Action: None. A Balance check doesn’t require an action; it is made as part of another action or as a reaction to a situation.
Special: If you have the Agile feat, you get a +2 bonus on Balance checks.
Synergy: If you have 5 or more ranks in Tumble, you get a +2 bonus on Balance checks.
