Merrell Size Chart
Footwear and clothing conversions for women, men and kids, in US, UK, EU, JPN and CM. Merrell footwear is sized by foot length, so matching the centimetre column is the most reliable way to get the right fit — and if you land between two sizes, take the larger one.
Women's Footwear US 5 – 11.5
JPN is your foot length in centimetres; CHN is the same length in millimetres.

Men's to women's footwear
Merrell does not publish a direct men's-to-women's conversion, because every foot is different. Match your measured foot length in centimetres instead.
Wide and medium widths
Many hiking styles are offered in both Medium and Wide. A wide fit adds roughly one centimetre across the forefoot for the same length.
Kids' Footwear US 1 – 7
Covers little kids, toddlers, pre-school and grade school. Baby sizes for water shoes and sandals start at US 0 (EU 15.5 / 8 cm).

Growing room
Leave about one centimetre — a thumb's width — between the longest toe and the front of the shoe. Any more and the foot will slide on descents.
Measure both feet
Children's feet grow unevenly. Trace both feet on the same sheet of paper, and always size to the longer one.
Unisex Footwear
Unisex sizing runs as men's sizing. Women should select a size and a half smaller than their normal US women's size — for example, unisex 7 equals men's 7 and women's 8.5.

The 1.5 size rule
Unisex 7 = men's 7 = women's 8.5. So if you normally wear a women's 9, order a unisex 7.5. Never order your usual women's number in a unisex style.
Widths stay the same
A unisex style is built on one last. If the model is offered in Medium and Wide, the width choice applies to both men and women ordering the same size.
Men's Sandals
Sandals use a different UK conversion than shoes — a men's sandal US 9 is a UK 8, while a men's shoe US 9 is a UK 8.5. Do not assume your shoe size carries over.

Adjustability
Most Merrell sandals use hook-and-loop straps at the heel, instep and forefoot, so minor width and volume differences can be tuned on the foot.
Water shoes
Closed water shoes follow the standard footwear chart. If you plan to wear them with neoprene socks, take the next half size up.
How to Measure Your Foot
Merrell sizes its footwear by foot length, so this is the measurement that matters most.
Prepare the paper
Place a sheet of paper on a hard floor against a wall, and put on the socks you will wear with the shoe.
Trace your foot
Stand with your heel touching the wall and your foot perpendicular to it. Draw a line just in front of your longest toe.
Measure both feet
Repeat on the other foot, then measure from the wall to each line. Use the longer measurement.
Match the chart
Find your length in the JPN column and read across to your size. If you fall between two sizes, take the larger one.
Check the toe box
Once the shoe is on, you should be able to press a thumb's width between your longest toe and the front of the shoe.
How to Measure Clothing
Bust / Chest
With arms relaxed at your sides, measure around the fullest part of the chest or bust, keeping the tape level.
Waist
Measure around the natural waistline — the smallest part of the waist, above the hip bones.
Hips
Standing with legs together, measure around the fullest part of the hips and seat.
Neck
Measure around the base of the neck where a collar would sit, keeping one finger under the tape.
Sleeve
Measure from the middle of the back, over the shoulder and down a slightly bent arm to the wrist.
Inseam
Measure the inside length of the leg from the crotch to the bottom of the ankle.
Finding Your Merrell Fit
Hiking & backpacking
The Moab family and most leather hikers run true to size with a roomy toe box and a secure heel hold. Take your measured length.
Trail running
Faster, lower-volume models fit closer to the foot. Runners with wide feet or who expect foot swell over long distances should go half a size up.
Barefoot collection
Zero drop, minimal cushioning and a wide toe box. Size by length as usual, but expect a very different feel underfoot — build up mileage slowly.
Waterproof models
A waterproof membrane slightly reduces internal volume. If you wear thick socks, some hikers prefer half a size up.
Sandals
Sandals have their own conversion, different from shoes and boots. Always check the sandal chart rather than reusing your shoe size.
Between two sizes?
Merrell recommends taking the size above. For footwear this is the safer choice; for clothing, follow the fit note on the product.
Care & Returns
- Returns: unworn, unwashed and unaltered items can be returned within 30 days.
- Footwear: try shoes on indoors first — worn outdoors they may not qualify for return.
- Care: air dry footwear at room temperature, away from direct heat. Never machine wash or tumble dry.
- Cleaning: brush off dried mud, then wipe with a damp cloth and mild soap. Refresh waterproofing as needed.
Conversions follow Merrell's published size guides for women's, men's, kids', unisex and sandal footwear, plus men's and women's clothing. Measurements are approximate and provided for reference only.
