La suola è consumata, però è riparabile.

Because suola and suolo are different words.

• la suola = the sole of a shoe
• il suolo = the ground / soil

They look very similar, so they are easy to confuse. In this sentence, la suola is the part of the shoe that touches the ground.

Because it agrees with la suola, which is:

• feminine
• singular

In Italian, adjectives and past participles used like adjectives must agree with the noun they describe.

So:

• la suola è consumata
• il tacco è consumato
• le suole sono consumate
• i tacchi sono consumati

This agreement is one of the first things English speakers notice, because English adjectives do not change form this way.

Here consumata means worn down, worn out, or used up from wear.

With shoes, consumato/a is very common for something that has been damaged gradually through use. So the sentence suggests that the sole has been worn by walking, friction, time, and use.

It does not necessarily mean completely destroyed. The second part, però è riparabile, tells you that it can still be fixed.

In this sentence, consumata is being used like an adjective: the sole is worn.

So è consumata describes the current condition of the sole.

You can also hear si è consumata, which focuses more on the process of becoming worn:

• La suola è consumata = The sole is worn.
• La suola si è consumata = The sole has worn down.

Both can be natural, but they are slightly different in focus:

• è consumata = state / condition
• si è consumata = action / process that happened over time

Both però and ma can mean but, and in many cases either one would work.

• ma is the most basic and direct word for but
• però often sounds a little more like however / though / still

So:

• La suola è consumata, ma è riparabile.
• La suola è consumata, però è riparabile.

Both are natural.

Using però can make the contrast feel slightly more emphatic: the sole is worn, however, it can still be repaired.

Because the sentence has two clauses:

• La suola è consumata
• però è riparabile

In Italian, però is often set off with punctuation, especially when it connects two full ideas. The comma helps show the contrast clearly.

You may also see però in different positions:

• La suola è consumata, però è riparabile.
• La suola è consumata; però è riparabile.
• La suola è consumata. Però è riparabile.

All of these are possible, depending on style and emphasis.

Because Italian still needs the verb essere in the second clause.

The full structure is:

• La suola è consumata
• (La suola) è riparabile

The subject la suola is omitted the second time because it is understood, but the verb è cannot be omitted.

English does something similar:

• The sole is worn, but it is repairable.

Italian often drops subject pronouns and repeated nouns when they are clear from context.

Riparabile means repairable, able to be repaired, or fixable.

It comes from riparare = to repair, plus the ending -abile, which often means able to be...

Examples:

• lavabile = washable
• leggibile = legible / readable
• mangiabile = edible / good enough to eat
• riparabile = repairable

So è riparabile means that the damage is not beyond repair.

Riparabile is perfectly correct and natural, especially in practical contexts such as shoes, clothing, objects, or mechanical parts.

You might also hear:

• si può riparare = it can be repaired
• si può aggiustare = it can be fixed
• è ancora riparabile = it is still repairable

For example:

• La suola è consumata, però si può riparare.
• La suola è consumata, però è ancora riparabile.

These are all natural alternatives.

Yes. Depending on the exact situation, Italians might use different words:

• consumata = worn down from use
• usurata = worn, often a bit more formal or technical
• rovinata = damaged / ruined
• danneggiata = damaged

For a shoe sole, consumata is a very good and idiomatic choice because it specifically suggests wear from use.

Because Italian often leaves out the subject when it is obvious.

In English, you need it:

• The sole is worn, but it is repairable.

In Italian, once la suola has already been mentioned, the second clause can simply say:

• è riparabile

The subject is understood from context. This is very normal in Italian.

Yes. It sounds natural, especially in contexts like:

• a cobbler examining a shoe
• someone describing damage to footwear
• a repair shop discussing whether an item can be fixed

It is clear, idiomatic, and practical. A native speaker would easily understand it.

A slightly more everyday version might also be:

• La suola è consumata, però si può riparare.

But the original sentence is absolutely good Italian.
