Even though Sony xm3 sounds beeter, astrotec still worth the money. This is what he has to say:This order was delivered promptly and came well packaged. They seem like they’re pretty sturdy and they’re easy to get on/off unlike other cycle shoes I have tried. These cables work just fine but when i compare to another Apple OEM Cable, i doubt these are true OEM I havent had them long enough to determine Durability. I went back to researching and came across the Samson, which also had great reviews. Bisher hatte ich nur schwarze Turnschuhe. They are perfect for my feet and at a fair price. Add to this, upon forgetting that these trashed my feet and trying them for a short outdoor walk again, the hard reinforced lip around the ankle went straight through "blister" to "raw" and now I have to peel my socks off a scab every night. Save your money and get a proper shoe rack. I received a few emails from the manufacturer to make sure I had the installation instructions.
