asics womens kayano 23

[JudithBoyle]

I've been running in ASICS GT 2150 since about Jan 1. In that time I've gone from running 30 seconds and then walking, to running 13-15 miles comfortably. To be honest, I bought the 2150s because the sporting goods store had them in a EEEE width, and knowing that my forefoot tends to splay and expand a lot on impact, I always go with a shoe wider than my foot measures. (Never one blister for me in the 2150).I bought a pair of Saucony Kenvara 2 in size 11 yesterday (that's about a half size bigger than I normally wear). They don't come in wide widths, none of the minimalist shoes they had seemed to (I'm wearing a EEEE in my Asics). The guy at the running store said that I do pronate a bit, but that doesn't mean it's a problem and it doesn't mean I'm benifiting from the support shoes. He advised me to keep an open mind while transitioning and perhaps even try using my superfeet inserts in the Kenvaras during the transition. The thing he seemed to stress the most was to only run no more that 10% of my weekly miles in the Kenvaras at first.

As a minimalist runner myself, I feel sometimes almost bad about selling heavily cushioned motion control shoes for lightweight people with only slight overpronation, but if someone comes to store and says "My doctor/physiotherapist told me to get a shoe with a lot of cushion and pronation support", who am I to tell that he's wrong? Maybe he is, maybe he isn't. Then I just sell the Asics Kayanos or Mizuno Nirvanas and hope for the best. And mention, that we also sell Vibram FiveFingers, which may help strengthen the feet. (They are becoming really popular in Finland, actually they are our best selling product at the moment.)The above may be true in Western countries but here in Japan you'd be hard pressed finding an ASICS shoe at a running store that isn't "Minimalist" ! So a representative of that company saying they, the company, rejects the value in minimalist shoes is just silly. He should come to the head office in Kobe and try to sell his Japanese counterparts on his ideas!

Generally, technology for solving the computationally intensive proof-of-work calculations involved in blockchain systems has evolved rapidly in recent years. For example, in the case of bitcoin transactions, the proof-of-work process involved in discovering valid transaction block headers was originally was conducted utilizing software applications running on general-purpose processors. However, speed and efficiency are paramount in proof-of-work systems, including those used within the context of blockchain systems. Accordingly, bitcoin mining operations have moved toward specialized hardware solutions, including ASICs. ASICs provide profound increase in speed and efficiency arising from the line-level speed with which calculations may be conducted. As the name implies ASICs are designed and fabricated to perform one specific application, in this case the mathematical operations involved in implementing a specific cryptographic protocol.

The success of the bitcoin network has evidenced the secure nature of blockchain technology. Accordingly, the use of blockchains in other related fields has gained interest over time. However, ASICs are designed to narrowly match specific elements of the protocol within which they are to be implemented, specifically the elements of the protocol describing the particulars of the proof-of-work system defined by the protocol. For the bitcoin network, each ASIC is designed assemble at great speed block headers as described by the bitcoin protocol, subject them to two consecutive instances of the 256-bit version of the Secure Hashing Algorithm (SHA-256) protocol, and finally check the validity of the resulting 256 bit binary hash value by comparing it to a pre-determined validity test, which in the case of the bitcoin protocol is embodied as the difficulty level, as was discussed previously.

This limits the flexibility and opportunity to proliferate blockchain technology outside of the bitcoin network itself, or of networks based or  chained' on it to one degree or another, since high-performance proof-of-work implementations generally require the use of ASICs, and current-generation ASICs are only able to implement one highly specific proof-of-work system. Moreover, due to the nature of the proof-of-work process any private blockchain that relies on the same proof-of-work system used by Bitcoin for its own proof-of-work process can easily be interfered with by third parties using commercially-available equipment designed to solve the proof-of-work system defined by the bitcoin protocol.

Before discussing the embodiments of the technology of the present disclosure in detail, it is helpful to discuss the overall workflow surrounding the processing of the proof-of-work operations involved in the network transaction verification of blockchain transactions by systems utilizing ASICs designed for this application.A direct bit inversion transformation scheme may also provide a straightforward means to disable all effects of the programmable transformation 215 by simply setting all values in the 256 bit configuration key to zero. Such a key may be referred to as a null key. One result of this it simplifies the process of configuring a transform-enabled integrated circuit 203 so that it operates in a manner undistinguishable from that of a comparable integrated circuit not incorporating the programmable transformation function 215 .
