I recently purchased some heat moldable insoles from Yoursole. I have had problems with hot spots on the ball of my right foot through several different brands of shoe.
Conclusion: I do not recommend these.
Details:
The last shoes I have owned are:
Avia
Shimano
Carnac Quartz (nice fit, poor construction, heavy)
Specialized Carbon Road (still have them)
Nike Poggio (current pair - a little snug)
I was hoping the custom insole would eliminate the hot spot. I bought the Slim Sport Footbed for $39.95 and a couple pair of socks. This model is for tight fitting applications like road biking shoes. They arrived fairly quickly. They look well constructed but what do I know? My first pair of after market insoles.
Per the directions I preheated the oven to 200 degrees. The soles have a dot on the bottom that turns black when the insoles are ready to be removed. I baked the insoles for the suggested two minutes but they were not even warm when I took them out. I noticed the dot had not changed colors so I put them back and watched until it did.
I immediately inserted them into the Nikes then put them on so they would mold to my feet. The next day I went for a 30-mile ride. I noticed I had a lot more room in the toe than with the Nike insoles. After about 20 miles my feet were really starting to hurt. It would go away if I concentrated on the upstroke but something just wasn't right.
I got home and removed the insoles. I compared them side by side with the insoles of other shoes. The heel and arc sections are great but the area under the ball and toe is very very thin and has more or less nonexistent cushioning - less than 1/8" thick. This part of the insole may as well be made of wood because thats what it feels like.
Here are some pics so you can see them compared to the Nike and Specialized insoles, both of which have additional padded section under the ball that the Yoursole model doesn't have. The Specialized are near 75% thicker under the padded ball area and the Nikes about 50% thicker.
They do have a 90-day exchange/refund guarantee so all is not lost.
Nike Poggio insoles on the left, Yoursoles in the middle, Specialized Carbon Road on the right. I would say the Specialzed is the best of the three. I'm going to ride the next week with those insoles in the Nike shoes.
On the Yoursole the black section under the ball of the foot is NOT extra padding like the other two. It's all one thin layer.
