Install a set of BBK performance underdrive pulleys and see an average of 8-15 additional horsepower over the stock pulleys. Under drive pulleys increase engine output by reducing the draw of the engines accessories by slowing them down and reducing the HP they use. Additional and significant performance improvements can be seen by reducing the weight of the pulley versus the original pulley which is why we recommend the BBK CNC Machined billet aluminum pulley kits for maximum horsepower gains. ALL BBK pulley kits are designed as direct bolt on replacements for the current factory pulleys and retain full cooling and charging characteristics. BBK under drive pulley kits are vehicle specific and each kit comes with complete installation instructions and allow the re-use of existing serpentine belts.

Perfect fit for 5'10
Size: 10 Long, Color: White
White jeans size 10 long fit perfectly. Im 5'10 130 pounds
Always have trouble with length and overall fit. These were on sale for less than 11$! Material has some stretch, not too much. I'm going to hang to dry don't want any shrinkage. Fit is less tight than an earlier version of these jeans.

great fit
Size: 4, Color: White
This is my third buy from this brand. They fit great, I have no problem with them at all, and you can't beat the price. You can dress them up with heels and a nice blouse, or wear them casually. I recommend them.

Loved them so much- Bought another pair
To start off, I have wide feet, ankles, and calves, because i'm a bit on the heavier side. Finding shoes that fit these requirements are difficult. The top part of the shoes that hug my legs are actually still a little roomy. Someone who has slightly larger lower legs can fit into these as well. If you have tiny legs, these shoes may be a little too loose, or if you don't have wide feet. These shoes are literally perfect for my feet and legs. The back unzips so I was able to get my feet into the shoes easily, and even wearing them I didn't feel like my toes were being squished. I ordered a size 10, and it is perfect length and width for my wide feet. Do note: My feet are wide enough to not fit in most shoes, but not too wide, you should pay attention to the measurements if you have wide feet.
I was a little skeptical from a review of a woman who had her toes bleeding from these shoes, as I know that is often a problem for me with most shoes I wear. Generally I start bleeding in the back of my heel. So I was skeptical that these shoes would make me bleed. However, I was proven wrong. These are one of the only shoes i've worn that haven't rubbed my skin right off. I believe that has to do with the lovely height of the back, which prevents rubbing on the back of your heels, and the perfect width of the shoes. If your feet are too wide for these shoes, then you will probably bleed, but that's to be expected because the shoe does not fit you and that is often something that can happen with shoes that don't fit.
I originally bought the green pair, because I loved the color, but then I loved the fit so much that I bought a second, black pair. These are one of the only shoes with heels I actually wear because they are more comfortable than most, and they're just adorable. I am not generally a high heel wearer, so I'm not used to walking with my heels elevated. Despite that, these shoes were fairly easy to walk in. They are my favorite pairs of heels. and I do highly recommend them.
I will be buying more colors in the future, and I hope they will come out with more colors like brown and an aqua/blue shade.
