Si ton talon te fait encore mal demain, mets aussi un peu de pommade avant de marcher.

Si means if here. It introduces a condition:

• Si ton talon te fait encore mal demain = If your heel still hurts tomorrow

This is a very common French pattern:

• Si + present tense, then a result, instruction, or future idea
• Example: Si tu es fatigué, repose-toi. = If you are tired, rest.

In this sentence, the second part is a command: mets aussi un peu de pommade...

Talon means heel.

Ton means your and is the masculine singular possessive form. It matches the noun talon, which is masculine singular.

French possessives agree with the thing possessed, not with the person who owns it.

So:

• ton talon = your heel
• ta main = your hand
• tes pieds = your feet

French often uses the expression faire mal à quelqu’un, literally to cause pain to someone.

So:

• ton talon te fait mal
  literally: your heel causes pain to you
  natural English: your heel hurts

A few examples:

• La tête me fait mal. = My head hurts.
• Le dos lui fait mal. = His/Her back hurts.
• Les jambes nous font mal. = Our legs hurt.

This structure is extremely common in French.

Te is the indirect object pronoun meaning to you.

In ton talon te fait mal:

• ton talon = the subject
• fait mal = causes pain / hurts
• te = to you

So the structure is:

• [body part] + faire mal à quelqu’un

When à quelqu’un becomes a pronoun, it changes like this:

• me = to me
• te = to you
• lui = to him/her
• nous = to us
• vous = to you
• leur = to them

Example:

• Le bras lui fait mal. = His/Her arm hurts.

Here, encore means still.

• te fait encore mal demain = still hurts tomorrow

Depending on context, encore can also mean again, so learners often find it tricky. Here the meaning is clearly still, because it refers to a continuing situation.

Compare:

• J’ai encore mal. = I still hurt / It still hurts.
• Dis-le encore. = Say it again.

French word order is often a little different from English. In this sentence:

• Si ton talon te fait encore mal demain

the time word demain comes naturally at the end of the clause.

French often places time expressions like this after the main verbal idea:

• Je pars demain. = I’m leaving tomorrow.
• Il revient ce soir. = He’s coming back tonight.

You could think of the sentence as:

• If your heel still hurts tomorrow...

Mets is the tu form of the verb mettre in the imperative.

• infinitive: mettre = to put / apply
• present tense: tu mets
• imperative: mets ! = put! / apply!

For -re verbs, the tu imperative usually keeps the final -s:

• mettre → mets
• prendre → prends
• attendre → attends

So:

• mets aussi un peu de pommade = put/apply a little ointment too

Because the speaker is talking to one person informally, using tu.

French imperatives have different forms depending on who you are addressing:

• mets = informal singular (tu)
• mettons = let’s put/apply (nous)
• mettez = formal singular or plural (vous)

So this sentence sounds like advice to one person the speaker knows well, such as a friend, child, or family member.

Aussi means also or too.

Here it suggests an additional action:

• mets aussi un peu de pommade = apply a little ointment too / also apply a little ointment

So perhaps the person is already doing something else, and this is one more suggestion.

Because the fixed expression is un peu de, meaning a little (of).

Even though pommade is feminine, un peu does not change to match it.

Think of un peu de as one chunk:

• un peu de pain = a little bread
• un peu d’eau = a little water
• un peu de pommade = a little ointment

So the gender of the noun after de does not affect un peu.

Pommade usually means ointment, salve, or sometimes a medicated cream depending on context.

In a sentence about pain in the heel, pommade most naturally means something you rub on the skin to soothe or treat it.

So mettre de la pommade means to apply ointment.

Because after avant, French normally uses de before an infinitive.

So:

• avant de marcher = before walking
• avant de partir = before leaving
• avant de manger = before eating

This is a standard pattern:

• avant de + infinitive

Here it clearly means to walk.

Marcher can mean:

1. to walk
2. to work / function for machines or systems

But in this context:

• avant de marcher = before walking

because the sentence is about a painful heel.

French often uses definite articles with body parts, especially when the body part is affected by an action:

• Je me lave les mains. = I wash my hands.
• Il a mal au dos. = His back hurts.

But French can also use a possessive adjective when the body part needs to be identified clearly or emphasized:

• ton talon = your heel

Here, ton talon sounds natural because the sentence is specifically about your heel as the topic of the condition.

So both article patterns and possessive patterns exist in French; the choice depends on structure and emphasis.

A careful pronunciation would be approximately:

Si ton talon te fait encore mal demain, mets aussi un peu de pommade avant de marcher.

Roughly: see ton ta-lon tuh feh ahn-kor mal duh-man, meh oh-see uh(n) puh duh po-mad ah-vahn duh mar-shay

A few helpful notes:

• si sounds like see
• talon has a nasal ending: ta-lon
• fait sounds like feh
• encore is often ahn-kor
• mets sounds like meh
• un peu de is often said smoothly together
• avant de marcher flows as one rhythm group

Also, in natural speech, French links words smoothly, so the sentence may sound more connected than the spelling suggests.
