Compare SDM Feet and SD13B/SDGrB Feet to find the right match for your doll. Learn key size differences, material details, and buying tips for Volks SD option parts.
Quick Answer
Choose SDM Feet for MSD and SDM-sized dolls, and SD13B/SDGrB Feet for SD13 Boys and SDGr Boys. Both are urethane resin pairs with UV protection, but they are not interchangeable across these size groups.
Why Size Groups Matter
Volks SD option parts are designed for specific doll size groups. The SDM Feet are made for MSD Girls, MSD Boys, SDM Girls, and SDM Boys, while the SD13B/SDGrB Feet fit SD13 Boys and SDGr Boys. These size categories have different proportions, so the feet are not cross-compatible.
If you are unsure of your doll's size group, check your doll's documentation or measure the current foot. Using the wrong size can lead to poor fit and instability when standing.
Material and Handmade Variations
Both feet are made from urethane resin with UV protection, which helps resist yellowing over time. However, because they are handmade, there may be slight color variations between batches. This is normal and does not affect function.
The product images are samples, so the included parts and final appearance may vary slightly. Expect minor differences in color or finish compared to the photo.
Trade-Offs at a Glance
- SDM Feet – Smaller Scale: Designed for MSD and SDM size groups. If you have an SDM or MSD doll, this is the correct choice. The smaller size may look disproportionate on larger SD13 or SDGr bodies. Measure your doll's current foot to confirm it matches the SDM scale before ordering.
- SD13B/SDGrB Feet – Larger Scale: Designed for SD13 Boys and SDGr Boys. These feet are larger and will not fit SDM or MSD dolls. They are ideal for taller, more mature boy bodies. If you are buying for an SDGrB, double-check the exact model name to avoid confusion with SDM sizes.
- Handmade Color Variation: Both products are handmade, so color may vary between batches. If matching an existing skin tone is critical, order a spare pair or be prepared for minor differences. Request a color sample if available, or buy both pairs at the same time to minimize mismatch.
