One fixes how your shoe fits. The other fixes that, and how your foot looks. Here's how to choose.
Search for help after toe loss and you will meet two products with confusingly similar names. They solve different problems, at very different price points, and the right choice depends entirely on what is bothering you. Here is the honest comparison.
A toe filler (or toe spacer insert) is a block of foam or soft silicone shaped to occupy the empty space in your shoe. It does three practical jobs well: it stops the toe box creasing and collapsing, it stops your foot sliding forward in the shoe, and it can help stop the neighbouring toes drifting into the gap. It is inexpensive, available off the shelf or via a podiatrist, and lives in the shoe rather than on the foot.
What it does not do is look like a toe. Barefoot, in sandals, at the pool, the filler stays in the shoe and the gap comes with you.
A custom toe prosthesis is worn on the foot. Made from an impression of your residual toe and colour-matched to your skin and nail detail, it restores the appearance of the toe itself, and because it physically fills the toe box, it does the filler's practical jobs at the same time. It is fitted by a registered clinician, made to a quality standard, and costs accordingly more than a foam insert.
Some patients wear a prosthesis day to day and keep a simple filler in sports shoes or work boots where appearance is irrelevant and the device can stay home. There is no rule that says one answer must cover every shoe you own.
If you are weighing it up, a conversation with a registered clinician costs nothing and will tell you what each option looks like for your foot. Find a clinician to arrange one.
