6GEL-RESOLUTION X
This shoe may feel spacious for men but snug for women. Consider adjusting a half size accordingly.
More Info
The GEL-RESOLUTION® X tennis shoe creates advanced stability and cushioning for players who like to control the game from the baseline.
DYNALACING™ technology has been strategically designed to hold when extra support is needed. This allows you to experience a locked-in feel when you're making quick transitions. There's also a two-piece midsole design that helps improve stability when your foot lands on the court.
DYNAWALL™ technology in the midsole now extends into the heel for added stability during lateral movements. It's a functional feature that's effective when you're running covering both sides of the baseline.
Lastly, the higher medial collar helps prevent ankle twisting when making abrupt cuts back and forth.

Size Guide
How to Measure Your Shoe Size
Follow these steps to determine your shoe size. Do this during or at the end of the day for accuracy, as feet swell throughout the day.
1. Place a piece of paper under your foot. Stand up straight and have your heel lightly touching against a wall.
2. Mark the tip of your longest toe and heel on the paper. Measure the length of your feet from heel to toe.
3. Repeat the steps for your other foot and compare the measurements with our size chart below.

Fit
For running shoes, we generally recommend sizing up a half size from your casual shoe size.

Shoes Width Guide
The standard (medium) width for women is B. Shoe boxes and labels will only identify widths other than standard. Within the shoes, wide and narrow widths are identified on the label, underneath the tongue. ie. T005N (2E)
When is additional shoe width needed?
Visible stretching or bulging on the sides of the forefoot material is a good indicator that additional width may be needed.
Please note that the differences in width between narrow, standard, wide, and extra wide are usually only a few millimetres and are proportional to the shoe size. Most of the additional width will be in the forefoot.
