Slippers & Shoes: Google Product Category Taxonomy IDs

The Google product category for slippers, and for every other type of footwear, is:

187 - Apparel & Accessories > Shoes

Use ID 187 or the full path in your feed’s google_product_category attribute. That single category covers slippers, sneakers, boots, sandals, heels, loafers, flip-flops, running shoes, and baby shoes. Google Merchant Center accepts either the number or the text path.

If that feels too simple, you’re not alone. Footwear is the branch where merchants most often go hunting for a category that doesn’t exist.

Let’s settle what’s actually in the taxonomy and where the detail you want to express really belongs.

One category for all footwear, on purpose

Unlike Clothing, which branches into pants, shirts, sleepwear, underwear, and more, the Shoes category in Google’s taxonomy is a single leaf. Open the official taxonomy file and you’ll find exactly one footwear line:

187 - Apparel & Accessories > Shoes

No “Slippers” child. No “Sneakers,” “Boots,” or “Sandals.” There is no deeper level to reach, so ID 187 is simultaneously the broadest and the most specific footwear category possible.

Whether you sell memory foam house slippers, leather Chelsea boots, or kids’ light-up trainers, the google_product_category value is identical.

So where does the granularity go? Into the attributes you control:

What you want to say	Where it goes	Example
It’s a slipper	product_type + title	Footwear > Slippers > Moccasin Slippers
Who it’s for	gender, age_group	female, adult
What size	size	9, 42 EU
Material	material	Suede, Memory Foam
Color	color	Gray

The product_type attribute is your own free-text taxonomy, and for footwear stores it does the heavy lifting that google_product_category can’t.

A feed line like product_type = “Men’s > Slippers > Hard Sole Slippers” gives Google rich relevance signals and gives you precise product groups to bid on in your Shopping campaigns. Skipping product_type on footwear is leaving structure, and usually money, on the table.

“Pair of slippers” vs. “slippers”: variants don’t change the ID

Plenty of taxonomy lookups add qualifiers: pair of slippers, pairs of shoes, set of sandals, slippers for women, fuzzy slippers. None of these change anything.

Quantity wording: footwear is inherently sold in pairs, and Google treats a pair as one product. A “pair of slippers” is ID 187. A 3-pack of slipper multipacks is still ID 187, with the bundle expressed through the title (“3-Pack”) and the multipack attribute if you’re submitting a true multipack.

Audience wording: “women’s slippers” and “kids’ shoes” still map to 187. Gender and age live in the gender and age_group attributes. There is no separate children’s shoe category; even baby booties are 187, with age_group set to “infant.”

Style and material wording: “fuzzy,” “orthopedic,” “leather,” “open-toe” are title and attribute material, never category material.

The rule generalizes across the whole taxonomy: descriptive words in a search phrase almost never correspond to a real category. The category captures what the product is at the level Google has chosen, and everything else rides along in dedicated attributes.

The footwear-adjacent categories that DO exist

While shoes themselves are one category, several related products have their own homes, and misfiling these is the actual classification risk in a footwear store:

Product	Category ID	Path
Shoe accessories (parent)	1933	Apparel & Accessories > Shoe Accessories
Shoelaces	1856	Apparel & Accessories > Shoe Accessories > Shoelaces
Boot liners	5567	Apparel & Accessories > Shoe Accessories > Boot Liners
Shoe covers	5385	Apparel & Accessories > Shoe Accessories > Shoe Covers
Gaiters	7078	Apparel & Accessories > Shoe Accessories > Gaiters
Socks	209	Apparel & Accessories > Clothing > Underwear & Socks > Socks

Two boundary cases worth flagging:

Slipper socks. Sock-shaped products with grippy soles sit on the line between socks and slippers. Classify by construction and marketing: if it’s knitted and sold as a sock, use 209; if it has a substantial sole and is sold as footwear, use 187.

As always, keep similar SKUs consistent rather than splitting one product line across both.

Insoles and shoe care. Cushioning insoles, deodorizers, and polish kits are not apparel at all; they live in other top-level branches of the taxonomy (foot care and shoe care areas).

If you stock them, look up their exact IDs in the taxonomy file or with the category finder rather than defaulting them into 187 or 1933.

3 footwear mapping mistakes to avoid

1. Inventing a slippers category. “Apparel & Accessories > Shoes > Slippers” looks plausible and appears in plenty of badly configured feeds.

It is not a real path, and Merchant Center will reject it or silently remap the product. Only 187 exists.

2. Leaving product_type empty because the category is generic. Since every shoe shares ID 187, your product_type is the main structural signal distinguishing slippers from hiking boots.

Feeds that skip it lump the entire footwear catalog into one undifferentiated mass, which hurts both relevance matching and your ability to manage bids by product group.

3. Misfiling accessories as shoes. Shoelaces submitted as 187 instead of 1856, or boot liners as 187 instead of 5567, are easy errors when a store’s WooCommerce structure keeps accessories inside the main “Footwear” category. Map accessory categories separately.

Mapping footwear categories automatically in WooCommerce

Footwear mapping is the easiest cluster to automate precisely because nearly everything resolves to one ID. With CTX Feed Plugin:

1. Go to CTX Feed > Category Mapping and create a Google Shopping mapping.
2. Point every footwear category in your store, slippers, sneakers, boots, sandals, all of them, to Apparel & Accessories > Shoes (187). Point your accessories categories to their own IDs (1856, 5567, and so on).
3. In the feed editor, map product_type to your WooCommerce category hierarchy so each shoe carries its full store path, like “Footwear > Slippers > Moccasins,” alongside the shared Google category. Map size, color, and material from your variation attributes in the same screen.

The result is the correct footwear pattern: identical google_product_category across the catalog, with all the differentiation flowing through product_type and attributes, kept current automatically as you add products.
