    If the shoe fits....ok that's lame, but basically it's true. In our opinion, getting the right fit with this shoe is paramount, even more so than with traditional shoes. This shoe really needs to fit you like a glove without the Boa.

  • Without a doubt, the biggest change in the Ultra Race 4.0 is the introduction of the BOA closure. This is a simple twist-type of closure that really fine tunes the fit of the shoe for superior comfort and support.
  • A very welcome change that a good number of runners will really enjoy is the lowering of the collar, particularly at the back of the shoe. It answers past issues of blisters near the heel and just around the collar.
  • A new upper called TekSheen is extremely light, adapts very well to the foot, and fairly breathable. This is the kind of upper every triathlete dream of and should work well for most runners too.
  • Holes are now fitted in the midsole to drain water. Drain holes are fantastic in lessening the risks of blisters and in preventing the shoe from taking on more weight.

Comfortable and snug best describe the fit and sizing of the Ultrace Race 4.0, which is very similar to the past version. The fit is narrow to medium all across the shoe. This is structured in this way to maximize the fine tuning benefits of the BOA. As always, runners who may want to get more space, especially in the toe box can always go up in size. Available widths are D and B while sizes are 7 to 14 for the men’s and 6 to 12 for the women’s.

The outsole is a combination of blown rubber for better traction and the Zoot ZPU pattern of rubber lugs for a sufficient bite on a multitude of surfaces. The rubber lugs also act as complementary elements in the protection and cushioning of the shoe.

Zoot’s premium midsole technology in the Z-Bound is used in this shoe. This midsole foam is very durable, resilient, and ultra-responsive despite being extremely light. Another technology in the midsole is the CarbonSpan+, which is technically a carbon fiber inserted in the midfoot to give torsional stability. It allows the heel and the forefoot to work separately for better and smoother transitions. This midsole material is also used in some Zoot running shoes.

Zoot uses a TekSheen upper that is noted for its stretch and adaptive nature. This helps provide the foot-hugging wrap of this shoe. The same can be said of the BOA closure. This type of closure relies on a dial that uses a thin, but very sturdy cable. This cable is attached directly to the overlays and the sole. By simply dialing in, runners can loosen or tighten the tension to get the right and best comfort zone. A simple pull of the dial releases the tension as well.
