KEEN Sandals - Size Review

Do KEEN sandals
run big
or small?

KEEN sandals, an American brand gaining attention for blending outdoor functionality with lifestyle appeal and continuously offering new value, can often pose a challenge when it comes to size selection.

In general, compared to other brands like NIKE and adidas, many models tend to feel “slightly smaller in size”. (*This is a personal impression when selecting the same labeled size as sandals from other brands.)

Below, we introduce the size impressions for seven different KEEN models, based on feedback from our in-store staff.

UNEEK Sizing

KEEN - UNEEK  Size Review

Instep Height Normal

Size Impression Slightly small

Male Staff Size

  • When wearing the usual men's size of 26cm, the width felt tight, and although the instep height and length were fine, the overall fit felt slightly small.
  • At 26.5cm, there was a bit more room at the instep and toes, and the width felt just right.
  • For those who usually wear women’s size 23.5cm, 23cm felt extremely tight, and even 23.5cm may cause discomfort as the toe area felt tight and the sole contours didn’t align well with the foot.
  • 24cm provided the best fit and balance, while 24.5cm had slightly more room at the toes.

Staff Review

  • Wearing the usual men's size 26cm felt slightly tight and could feel uncomfortable for walking around town. The toebox, however, felt just right.
  • The 26.5cm size had a bit more room and felt optimal for city walking. There was a slight extra space in the toebox.
  • For those who usually wear women’s size 23.5cm, the 23cm felt too tight to wear, and the 23.5cm had slight discomfort at the heel and toe.
  • The 24cm provided a snug, comfortable fit. For those wanting a bit more room in the toebox, a half-size up is also recommended.

WHISPER Size

KEEN - WHISPER Size Review

Female Staff Worn Size

Usual Size 23.5cm
(Size worn for adidas STAN SMITH)
Instep Height Normal
Foot Width Normal
Toe Fit Normal
Size Worn 23.5cm
Fit Impression Runs small

Staff Review

  • For those who usually wear women's size 23.5cm, 23cm may feel too tight to even wear. With 23.5cm, if you align your foot with the insole shape, the heel slightly protrudes, and if you match the heel, the toe area feels slightly tight.
  • 24cm offers a perfect length and a bit of room in the toe area, making it comfortable.
  • 24.5cm does not look overly large and feels slightly roomier. It can also be recommended for those with wider feet or who prefer a slightly looser fit.

Staff Review

  • Wearing the usual men's size of 26cm felt slightly small, and it may feel too tight and stressful for walking around town or in active situations.
  • 26.5cm felt just right and offered great mobility. Putting them on and taking them off was also smooth.
  • 27cm had some overall room, and the foot lifted inside the shoe while moving.

  • Although 23.5cm in women’s sizing usually fits well, both 23cm and 23.5cm felt quite tight and are not recommended.
  • There isn’t a significant difference in length between 24cm and 24.5cm, only a slight variation in toe room.
  • A half-size up from your usual size is recommended.

  • When wearing the usual men's size 26cm, it felt slightly tight despite being roomier than 25.5cm.
  • Size 26.5cm was a perfect fit, offering ease of movement and being ideal for walking around town.
  • The width may feel slightly tight at first, but it is likely to stretch and conform with continued wear.
  • This model is mostly constructed with rubber laces, giving it more of a sneaker-like feel rather than a sandal.

  • With an open-toe design, the width and instep area can be fully adjusted, allowing for flexibility in sizing.
  • For those who prefer a compact look for their feet, the usual women's size of 23.5cm is fine, but 24cm is recommended as it provides better toe coverage.
