Slippers for Big Feet: Large Sizes and How Slipper Sizing Runs

Slippers for big feet are easiest to find in numbered sizes or the top letter size of a men’s line. On the Dearfoams chart, men’s X-Large covers US 13 to 14. Measure your longest foot late in the day, compare it to the foot length on the chart, and pick the next size up if you fall between two.

How large slipper sizes run on a letter chart

Large slipper sizes often come as letters, and each letter spans two shoe sizes. Here is how one maker, Dearfoams, sets the top of its women’s and men’s charts:

Both of these charts stop at X-Large, though Dearfoams lists XX-Large among its sizes. If your foot is longer than the last line, look for a style sold in numbered sizes instead. Other makers set their own charts, so treat this one as an example.

Women’s slippers for big feet: try a men’s or unisex size

Women’s slipper ranges usually end lower than men’s. Dearfoams’ women’s chart tops out at US 11 to 12, while its men’s chart goes to 13 to 14.

The unisex chart is the bridge. Dearfoams says a women’s size runs two above a men’s, so a men’s 7 matches a women’s 9 and a men’s 10 matches a women’s 12. A women’s 13 would sit near a men’s 11, the start of men’s Large.

Plenty of moccasins, clogs and slipper boots come in neutral colors that suit anyone. Our men’s slippers guide compares those shapes, and our women’s slippers guide covers the women’s range.

How to measure big feet for slippers

Big feet need a measurement, not a guess from an old pair. AAOS gives a few rules that apply to any footwear:

• Measure every year. AAOS says “feet can grow as we age.”
• Stand up. Your weight lengthens and spreads the foot.
• Measure late in the day. AAOS says feet may swell “up to 8%” during the day.
• Use the larger foot. AAOS notes that one foot may be slightly larger than the other.

Mark your heel and longest toe on a sheet of paper, then measure the gap in inches. Compare that number with the foot length column on the chart, not only the shoe size. AAOS also suggests about 1/2 inch between your longest toe and the end of the shoe.

Why one size does not fit every big-feet slipper

Slipper sizing for big feet varies more than the label suggests. AAOS says “the size may vary from brand to brand and from style to style” and advises against buying “based only on the size.”

That matters most at the top of the range, where there is no next size to fall back on. A snug moccasin and a roomy clog in the same size can fit quite differently. Minnetonka says its moccasins “should fit snugly” at first and stretch to the foot over time. Our moccasin slippers guide explains that fit.

What to check on a large-size slipper listing

A large-size slipper listing should answer four questions before you order:

1. Is the size a letter or a number? If a letter, find the chart and the foot length it covers.
2. Is it a women’s, men’s or unisex size? Convert using the maker’s chart if needed.
3. Is there a width? W or EE adds room across the foot. Minnetonka uses W for wide and EE for extra wide.
4. Does the lining take up room? A thick pile or sheepskin lining fills the inside more than a knit one, in our reading.

If none of the shapes fit, warm socks with a gripping sole can cover the gap. Our slipper socks guide explains when socks alone will do.

More help choosing slippers

Slippers for big feet still need the same checks as any pair: a sole that grips your floors and a back that holds the heel on stairs. Our slippers guide covers soles, linings and washing.
