Train Harder. Recover Faster. Look Like You Meant It.
The BEICSI Apex is built for people who take their performance seriously — and their style even more so. The all-black colourway keeps things focused and intentional, while the blade sole technology gives you the kind of responsive energy return that makes every stride feel lighter. Whether you're putting in miles or just moving through your day at full pace, this is the shoe that keeps up without slowing you down.
- You move faster with less effort — the blade sole is engineered to return energy with every step, so you can push further without burning out
- You feel like a serious athlete the moment you lace up — the sharp, all-black performance silhouette sends a message before you even start moving
- Your joints take less of a beating — the cushioned midsole absorbs impact on hard surfaces, protecting your knees over long distances
- You stay locked in no matter the pace — a secure lace-up fit means the shoe moves exactly where you do, with zero slipping
- You get performance and style in the same shoe — built for the track but sharp enough for everywhere else, so you're never changing twice

How to measure your foot
1
Prepare & trace
Place your foot on a sheet of paper. Trace around it holding the pen vertically against your foot.
2
Measure length
Draw a straight line from the back of your heel to the tip of your longest toe. Measure in cm.
3
Measure in the evening
Feet swell during the day. Measuring in the late afternoon or evening gives the most accurate size.
4
Use your larger foot
Most people have one foot slightly larger. Always size to your bigger foot and go up if between sizes.

Order your usual size.
