Yeezy Foam Runner MX Sand Grey: Size Guide, Fit & Review

The Yeezy Foam Runner MX Sand Grey fits roomier than the US-made solid colorways: taking your usual Yeezy size works, but expect a bit of heel slip. Two owner tricks from the release threads: thicker socks tame the heel slip, and one owner who sized up shrank the pair to his foot with the dryer trick. Owners also rate it among the best Foam releases visually. Below you’ll find owner reviews, a sizing guide, a FAQ and where to buy.

Yeezy Foam Runner MX Sand Grey Review

Here is what owners are saying:

“I took my regular Yeezy size (10US, my TTs is 9.5US) and they fit ok. The heelslip on the right sneaker is true. You can feel it a bit but I do not mind.” (r/yeezys)

“I would recommend to size up. I sized up since I was not sure and did the dryer trick to size them better to my feet. Now they fit perfect” (r/yeezys)

“Best foam released and honestly one of my top sneakers of the year.” (r/yeezys)

Yeezy Foam Runner MX Sand Grey Sizing Guide

Roomier than the solids

The MX line is made in China and owners consistently report it fits roomier than the US-made solid colorways. Your usual Yeezy size (typically half a size above true) works for most.

Heel slip and how owners fix it

• Some heel slip is normal on this pair; good socks reduce it.
• One owner who sized up used the dryer trick (short low-heat cycle) to shrink the foam to his foot. Do this at your own risk.

Yeezy Foam Runner MX Sand Grey FAQ (based on owners’ reviews)

Does the Yeezy Foam Runner MX Sand Grey run big?

Slightly roomier than the US-made solid colorways per owners with both. Usual Yeezy size works; sizing up adds noticeable heel slip.

Is heel slip normal?

Yes, an owner confirms feeling it at his regular size without being bothered. Thicker socks help.

What is the dryer trick?

An owner who sized up put the pair through a dryer cycle to shrink the foam closer to his foot and reports a perfect fit afterwards. It is a community hack, not an official method, so proceed carefully.
