If there’s one area where the Kiprun Kipsummit Race sparked the most discussion, it’s the upper.
"Once on foot, the lockdown is excellent and I had a lot of confidence in the fit. The only negative for me in the upper was the toe box friction on the outside of my big toes and a little lace bite over longer miles."
"The 'ghillie loop' lacing system combined with a pretty stiff heel work really well in tandem for keeping the shoe locked down over long/fast efforts. I did develop some hotspots on the heel and top of my foot during the break in period with this shoe."
On one hand, both testers appreciated the secure, race-ready lockdown. The integrated gaiter-style design creates a snug, almost sock-like fit that helps keep debris out and your foot in place, which is especially useful when moving quickly over uneven terrain.
But that same design also comes with some tradeoffs.
Both Abby and David noted that the upper can feel restrictive and unforgiving out of the box, particularly in the forefoot. The toe box runs on the shallower side, and runners with wider feet may find it limiting, especially over longer efforts.
Sizing is worth paying close attention to here. The performance-oriented fit, combined with the shallow toe box, means this shoe may not feel like a typical true-to-size experience for everyone. David opted to size down slightly and found success with a more dialed-in fit, while others may prefer sticking with their usual size but should expect a snug, race-day feel. If you’re between sizes or prefer extra room in the forefoot, this is not a shoe that offers much wiggle room.
There’s also a noticeable break-in period. Early miles brought some combination of friction, pressure points, or general discomfort before the materials began to relax and adapt.
For David, dialing in the fit took some patience, but once he got there, the lockdown worked well—even over the course of a 50K effort. Abby had a more neutral experience overall, but still noted that the fit feels performance-oriented rather than accommodating.
Ultimately, this is a race-focused upper: lightweight, secure, and streamlined, but not especially forgiving.
