That said, I’m not sure it’s going to replace the Nike Invincible or Hoka Bondi 7 for my easy training miles. If I review this shoe as a shoe for easy runs, which is what I’d argue it’s designed to be, it’s comfortable, rolls nicely underfoot and has seen me through runs up to 10 miles (16km) without any complaints. The men’s UltraBoost 22 weighs 333g, compared with the UltraBoost 21 which weighs 340g. Weighing 286g, the shoe is slightly lighter than the UltraBoost 21, which weighs 297g, but it still feels pretty hefty underfoot during a progression run or speedier miles. This isn’t necessarily a bad thing – if you’re a beginner looking for a shoe that can cope with faster paces, the firmer foam is better than anything too squishy, but personally, I miss the plusher feel of the older Boost models. It’s definitely stiffer and less comfortable than previous UltraBoosts and has a similar running experience to the UltraBoost 21. That said, compared with the midsole of, say, the Nike ZoomX Invincible Run, I wouldn’t call the UltraBoost foam soft. The holes in the foam of the shoe are larger and more flexible, designed to give a softer landing underfoot. I also didn’t have any issue with blisters and ran pretty comfortably in these straight out of the box.ĭuring the launch event of the UltraBoost 22 in London, Adidas designers explained how the Boost midsole foam has also undergone some changes for the female-specific UltraBoost. Considering you’re running on such a thick wedge of foam the shoe felt remarkably stable, even on faster sessions on wet, slippery pavements. Adidas says this is based on scans of female feet and is designed to prevent heel slip and blisters, as well as helping the shoe fit more securely. The instep is narrower in the UltraBoost 22 and sits slightly higher on the ankle. The tongue is also now more cushioned, which feels reassuringly comfortable.Īdidas Ultraboost 21, left, and Adidas Ultraboost 22 (Image credit: Adidas) This small change seemed to prevent the pressure and hot spots I’ve experienced on the top of my foot. There’s still the same plastic lace system as in its predecessor, but the lower laces are connected with two material loops rather than going through the plastic. I’m a UK 5 and found the shoe to fit true to size. It’s still sock-like, but I no longer feel like I’m losing the circulation in my toes after walking home from parkrun, with the bootie upper feeling like it has a lot more give. Adidas has used Primeknit+ yarn, which contains 50% recycled plastic, to create an upper that has more structure and support. The shoe definitely feels more comfortable underfoot. The result? I’ve run approximately 50 miles in the shoe, over a number of different sessions, and am impressed with the fit. Adidas says the tweaks to the upper and the fit of the UltraBoost 22 make the shoe 4% more efficient underfoot than the UltraBoost 21 for female runners. The shoe has the same extended heel as the UltraBoost 21, designed to make the shoe more comfortable for heelstrikers, and the same Linear Energy Push system on the outsole to produce a snappier toe-off.
