What is the Nailed Shoe?

There is a long, strange, and entertaining sugiya (discussion) about 'nailed shoes' early on in Shabat.  It is an example of the kind of fun material that I think doesn't get enough exposure.  G-d willing I will post a translation of it sometime soon.

Introduction

I am going through Shas (the Babylonian Talmud) very slowly - about 2 pages a week.  I'm hoping to post here about gems that I find along the way.  They will probably fall into three categories - the beautiful, the gross, and the just plain strange.
