K-Swiss Ultrashot 4
Pros & Cons
Details
Model Name: Ultrashot 4
Price: $165.00
Court Type: Hard
Summary (Gel-Resolution 9 alternative?)
The Ultrashot is one of the more premium models in the K-Swiss lineup, designed as an all-around option for players who want a mix of comfort and great support.
With its wide range of features, the Ultrashot also comes with added weight. At 16.2 ounces (460 grams), it is among the heaviest tennis shoes across brands. For reference, Asics’ Gel-Resolution X and Nike’s GP Zoom Challenge 1 weigh slightly less at 16.1 ounces (456 grams).
This level of weight is typical for cushioned, stability-focused tennis shoes because the extra mass adds structure that supports the foot during demanding movements.
When I tried the Ultrashot 4 on, they felt quite snug around the midfoot. The toebox was also noticeably narrower compared to the Hypercourt Pinnacle, which suited me better overall since my feet are medium-narrow. Because the shoe felt tighter all around, it gave a solid sense of support and stability.
In terms of comfort, the shoes were quite good. The sole area is well-cushioned, and there’s a good amount of padding around the heel and ankle. During my play sessions, I didn’t experience any soreness during or after. That said, the narrow midfoot area did cause a bit of pressure, though not in an uncomfortable way.
Since the Ultrashot 4 is packed with features, it weighs in at 16.2 ounces (460 grams), making it the heaviest model among major tennis brands. However, they didn’t feel clunky or overly bulky on court, and I would say that they are agile for their weight.
The two main drawbacks I found with the Ultrashot 4 were its durability and overall material quality. Priced between $165 and $170, it falls into the premium category.
However, when compared to similarly priced models such as the Hypercourt Pinnacle (approximately $180), the materials used in the Ultrashot 4 did not feel quite as premium. The upper is primarily mesh with some thin rubber overlays, and there is minimal reinforcement in high-wear areas.
These factors raised some concerns about long-term durability. After around five hours of playtesting, noticeable wear was already visible on the outsole grooves, likely due to their sharp and narrow shape.
Overall, the Ultrashot 4 provides a solid on-court experience, comparable in many ways to the Asics Gel-Resolution 9, which was discontinued in 2025. The shoe offers strong support and stability, allowing for quick and confident changes in direction. However, when compared to the Gel-Resolution 9, it falls slightly behind in both durability and toebox fit.
For players seeking excellent lateral stability and support, the Ultrashot 4 is a great option. It may not be the most durable choice, but for those who prioritize stability, the trade-off could be worthwhile.
Special Features
- DuraMesh and DuraPrint technologies provide a balance of support, comfort, and breathability.
- ShockFrame plate integrated into the heel enhances shock absorption and overall support.
- 360° Plantar Support Chassis improves stability around the midfoot and heel.
- Aosta 7.0 outsole with a multidirectional herringbone pattern is designed for increased durability.
Material Quality 8.5/10
The Ultrashot 4 is made with somewhat average materials, considering its hefty price tag. Some parts of the shoe are particularly well-made, such as the bottom of the heel, which features an impressive ShockFrame. Aside from that, the upper is constructed mainly from lightweight mesh with rubber strips arranged in a herringbone pattern.
Since the Ultrashot 4 is designed with support and durability in mind, the overall construction feels a bit more prone to wear. The sole has a pattern with sharp and deep grooves that provide excellent grip, but these grooves tend to wear down quickly. After just five hours of playing, the corners of the grooves had already begun to show signs of wear.
Overall, the Ultrashot 4 offers good material quality in certain areas, but some parts of the shoe may wear faster than expected, given its higher price point.
Comfort 9/10
Cushioning: The shoes are cushioned extremely well, especially in the ankle area. During play, they feel soft yet responsive.
Stiffness: The shoes have medium to high stiffness and provide excellent support and pushback.
Heel: The heel area feels cushioned and extremely well-damped.
Toes: The toebox is narrower than in the Hypercourt Pinnacle model and provides a fairly snug fit.
Prolonged use: During longer playing sessions, you might feel some pressure in the midfoot area, though it didn’t bother me.
Support And Stability 9.5/10
Lateral support: The shoes provide excellent lateral support despite lacking visible reinforcements on the outer.
Ankle support: The ankle area is well supported, and the ankle does not move unintentionally inside the shoe
Arch support: The arch of the foot has neutral support, making it suitable for players with over- or under-pronation.
Agility 9/10
Changes of direction: The shoes are surprisingly agile for their weight and don’t drag in the game.
Speed: because of their weight, the shoes are medium fast. Players looking for maximum speed might prefer the Hypercourt Pinnacle model.
Flexibility: Ultrashot 4 shoes are designed to be stable and supportive. Regardless of the stiffness still offers good playing comfort.
Grip 9.5/10
Sole shape: The sole of the shoe consists of a flat section with deep and sharp grooves.
The grip on the court: Thanks to the deep and sharp grooves, the shoes offer an excellent grip on the court.
The grip in long use: The grip of the shoes remains good even during long playing sessions.
Breathability 9/10
Moisture: For a stability and support-focused shoe, the Ultrashot 4 offers a surprisingly good moisture control. This is made possible through the mesh surface on the outer with less rubber coating than on average shoes.
Weight 8.5/10
Compared to other tennis shoe models, the Ultrashot 4 is one of the heaviest models. However, because of the snug fi,t the shoes feel agile for their weight.
The Fit 9/10
Size in general: the shoes fit well, so there’s no need to choose a size smaller or larger. For example, with Wilson’s shoes, I usually have to choose a size larger, as their shoe size does not match the general shoe sizes.
Width: The shoes are somewhat narrow in the midfoot area, so some players might feel a bit of pressure. The toebox is snugger than in the Hypercourt Pinnacle model, though it could still be a bit tighter.
Adjustability: The fit of the shoes can be adjusted well with the laces, and the laces hold well. There is no feeling that you should tighten the laces midplay.
Value For Money 8/10
Price range: The Hypercourt Pinnacle is priced at 165-170 dollars, placing them in the higher “flagship” price category. Shoes in this range are intended for demanding and performance-focused players.
Lifespan: The shoes are made from average-quality materials, and I would estimate they last around six months or a bit less. If you’re looking for a long-term shoe, the Ultrashot 4 might not offer the best value for the price. However, if you prioritize stability and support and don’t mind a shorter lifespan, then they could be worth it.
