I have never seen these before. Nice! Unnecessary, but NICE! Why did I say that? Because its not about the shoes you wear or what you look like or the kind of work you do... its about knowing God and sharing what he has done for you the best that you can. Take a minute and look at this passage from the book of Romans and see if it doesn't give all this a little bit more insight.

Rom 10:1-17 Brothers, my heart's desire and my prayer to God is for Israel, that they may be saved.2 For I testify about them that they have a zeal for God, but not according to knowledge.3 For being ignorant of God's righteousness, and seeking to establish their own righteousness, they didn't subject themselves to the righteousness of God.4 For Christ is the fulfillment of the law for righteousness to everyone who believes.5 For Moses writes about the righteousness of the law, "The one who does them will live by them."6 But the righteousness which is of faith says this, "Don't say in your heart, 'Who will ascend into heaven?' (that is, to bring Christ down);7 or, 'Who will descend into the abyss?' (that is, to bring Christ up from the dead.)"8 But what does it say? "The word is near you, in your mouth, and in your heart;" that is, the word of faith, which we preach:9 that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved.10 For with the heart, one believes unto righteousness; and with the mouth confession is made unto salvation.11 For the Scripture says, "Whoever believes in him will not be disappointed."12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, and is rich to all who call on him.13 For, "Whoever will call on the name of the Lord will be saved."14 How then will they call on him in whom they have not believed? How will they believe in him whom they have not heard? How will they hear without a preacher?15 And how will they preach unless they are sent? As it is written: "How beautiful are the feet of those who preach the Good News of peace, Who bring glad tidings of good things!"16 But they didn't all listen to the glad news. For Isaiah says, "Lord, who has believed our report?"17 So faith comes by hearing, and hearing by the word of God. WEB

Sharing what Jesus has done makes you beautiful; no matter who you are. Even if you are 15 and have pimples or seventy and grey hair, you have beautiful feet; the Bible says it and its true. Not everyone will like you and that is just the way it is, but the fact is that you are still beautiful. So, go ahead and buy the sneakers or don't buy them; either way... you are beautiful.
