The original Kyosho Nitro USA-1 set the standard for RC Monster Truck power and performance when it was released in 1990. 30 years later, the torch has passed to the newest Nitro USA-1, which outperforms the original in EVERY respect. Yes, it's that much better… and Kyosho even built it for you.

Built on a pickup truck chassis, large diameter tires and big engines with massive horsepower were installed by fun-loving American off-roaders to create the monster truck. These ever-popular monster trucks can be seen on specially-made racing circuits or jumping rows of cars in stadiums across the USA. Many R/C monster truck models have been produced over the years. First among equals is the legendary 1/8 scale USA-1 that embodied the might of American trucking power during the 1980’s and 90’s. Officially licensed by Kyosho in the 1990’s, the R/C model uniquely captured the power and glory of the USA-1. Now it’s ‘comeback-time’ for the USA-1, with modern chassis and drivetrain technology, upgrades unique to the USA-1 throughout, and a newly-designed ‘ULTRA SCALE BODY’ with form and detail finished to display-model standards. The iconic American flag graphic emblazoned on the body makes your heart swell with pride! The chassis features shaft-driven 4WD and 5-link suspension based on the Mad Crusher 2.0 & FO-XX models. Most of the suspension components have been uniquely upgraded and reinforced for the USA-1 at each point to handle the powerful new KE25SP2 engine, and the rigors of monster trucking. A 3-speed automatic transmission produces dynamic acceleration, which is enhanced by a true suspension system to produce "scale" running characteristics worthy of the prestigious USA-1, and make you feel like a monster truck driving god. Released as a pre-assembled Readyset, the USA-1 is almost ready for action straight out of the box.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
