The full process, the corner cuts, the fastening pattern and the cleanup all live in the Standard guide: [How to Install Base Shoe](/learn/install-base-shoe/). Read that first, then come back here for the differences. ## Introduction Baby shoe is [base shoe](/glossary/moldings/#base-shoe) that has been ripped down narrower on the table saw. You use it where a [stair nosing](https://letsbuildstuff.co/learn/install-wood-nosing/) meets hard surface flooring, and there is not enough room for a full height piece of shoe. The flooring crew butts the hard surface flooring into the face of the nosing. It gets close, but never perfect, so there is a joint along the front and the returns that has to be covered. Standard shoe is too tall for it and would stand proud of the nosing. So you [rip](/glossary/joints-and-cuts/#crosscut-vs-rip) a piece down and run it around the nosing, sitting on the floor and tight against the face. ## What Is Different From Standard Base Shoe - **Where it goes:** around a stair nosing on hard surface flooring, not along a wall at the [baseboard](/learn/install-baseboard/). - **The material:** 5/16" shoe, ripped down from stock shoe on the table saw. You do not buy it at this size. - **The height it works to:** the shoe is sized off the exposed face of the nosing, not off a fixed number. Exposed face = nosing thickness minus flooring thickness. Our usual job is a 3/4" nosing and 1/4" flooring, so 1/2" of face is showing, and a 5/16" shoe leaves a 3/16" reveal of nosing above it. - **What holds it:** [23-gauge pins](/recommends/dewalt-dwpn23100-amazon), not 18-gauge brads. At 5/16" a brad splits the piece. - **What it pays:** baby shoe typically charges and pays out at double the standard [base shoe](/learn/install-base-shoe/) rate, because of the table saw rip. Everything else follows the Standard guide. Same profile matching, same species rules, same joint work, same handling at punchout. ## Before You Begin ### Prerequisites - The hard surface flooring is finished and in place. - The nosing is set, and you know its thickness and the flooring thickness. Those two numbers are what size the shoe. Check them before you rip anything. - You have read [How to Install Base Shoe](/learn/install-base-shoe/). This guide does not repeat it. ### What You Need To Know Do the subtraction before you rip anything. Nosing thickness minus flooring thickness is how much nosing face is showing, and the shoe gets ripped to leave a 3/16" reveal of that face above it. Change the flooring and the rip changes with it. 5/16" is the answer for 1/4" flooring under a 3/4" nosing, it is not a number to reach for every time. Rip the whole run at once. Set the fence, cut everything you need for the job, and you only set up the saw one time. ## Tools Required Same kit as the Standard guide, plus one addition. - **Table saw** - to rip the shoe down to 5/16". This is the tool that makes baby shoe its own job. - **[23-gauge pin nailer](/glossary/tools/#23-gauge-pin-nailer)** - baby shoe gets pinned, not bradded. A 5/16" piece is too thin to take an 18-gauge brad without splitting. - Miter saw, compressor and hand tools: see [How to Install Base Shoe](/learn/install-base-shoe/). ### Materials Stock base shoe to rip down. Match the profile and the species to the rest of the shoe on the job, and follow the same pre-painted rules as the Standard guide. ## How to Install Baby Shoe Step by Step ### Step 1: Check the Nosing Height Measure the exposed face of the nosing, from the top of the finished floor to the top of the nosing, at several points along the run. Note the smallest measurement you find, because that is the one your rip has to suit. Subtract the 3/16" reveal from it and that is your shoe height. ### Step 2: Rip the Shoe Set the table saw fence to 5/16" and rip your stock shoe down. Keep the finished face of the profile; the rip takes material off the back or the top depending on how the profile runs. Rip everything the job needs in one setup. Going back to reset a fence for two more feet of shoe costs more than the material. ### Step 3: Cut Around the Nosing Run the baby shoe around the nosing: across the front, then out to each return. Cut the corners the same way you would on standard shoe, and dry fit the whole run before you put a nail in anything. ### Step 4: Nail It Off Pin into the nosing or the riser behind it. Never pin into the finished floor. Same rule as standard shoe: the flooring has to stay free to move, and a fastener through the shoe into the floor pins it down. Use 23-gauge pins. At 5/16" there is not enough material to take an 18-gauge brad, and the pin leaves a hole small enough that it needs almost nothing to fill it. ## Quality Check - The shoe sits tight to the floor with no shadow gap underneath. - The shoe sits tight against the face of the nosing along the whole run, with an even reveal of nosing showing above it. - Corners and returns are tight, with the joints filled and sanded flush. - Nothing went into the finished floor. Pins are in the nosing or the riser. - The ripped edge is not visible from a standing position. ## Troubleshooting ### The nosing face is shorter in one spot Rip to the smallest face you measured, not the average. A piece sized to the short spot still looks right where the face is taller, it just leaves a slightly bigger reveal there. A piece sized to the tall spots will stand proud of the nosing wherever the face is short. ### The thin piece splits when fastening You are almost certainly on an 18-gauge brad. Switch to the 23-gauge pinner. Ripped shoe has far less material around the fastener than full height shoe does, and the brad is what is wedging it apart. ### Pins are not holding Check what you ripped down. 23-gauge pins do not grip in MDF, because there is no grain for the barbs to bite (see the same issue in [How to Install Base Shoe](/learn/install-base-shoe/)). Poplar is the usual painted shoe and it takes a pin fine. If you are stuck with MDF, a drop of CA glue in the hole right after pinning will hold it. ## Related Guides - [How to Install Base Shoe](/learn/install-base-shoe/) - the Standard guide this Variant is built on. - [How to Install Stair Skirt Boards](/learn/install-skirt-boards/) - the other stair trim that has to fit around finished surfaces. - [Install Pre-Cut Shoe Molding, Nail Down](https://letsbuildstuff.co/learn/install-pre-cut-shoe-molding/) - [How to Install Notched Skirt Boards](https://letsbuildstuff.co/learn/install-notched-skirt-boards/) Written by **David Hospodka**, Sun’s Up Construction David Hospodka learned finish carpentry from his father, alongside his brother Joel, and worked his way through college trimming houses.
