When we launched Senderella Lite, our free climbing shoe generator, we were overwhelmed by the support and engagement from the climbing community. From passionate Reddit threads to thoughtful Instagram DMs, climbers shared valuable feedback that helped us better understand their needs. Inspired by this insight, we developed Senderella+, a smarter, more refined tool that helps climbers find the perfect pair of shoes with greater precision and ease.

Listening, Learning, and Iterating
Senderella+ was born from the collective voice of climbers worldwide. After thousands of users tested the original version, it became clear that while the foundation was solid, there was room to grow. Many climbers wanted more nuanced fit recommendations, clearer specs, and a better way to evaluate their options. Senderella+ delivers all of that—and more.

What’s New in Senderella+
1. Personalized Size Recommendations
One of the most-requested features was a better sizing system. Senderella+ now offers tailored size suggestions for both comfort and performance fits. These recommendations reflect actual user data and acknowledge that sizing can vary drastically between brands and even individual models. Whether you’re looking to crush long multi-pitches or project steep boulders, we’ll help you find a size that works for your goals—and your feet.
2. Comprehensive Shoe Breakdowns
Each shoe listed on Senderella+ now includes a detailed breakdown covering:
- Closure system (lace, Velcro, slipper)
- Rubber type
- Retail price
- Materials
- Curvature (aggressive, moderate, neutral)
This transparent view lets climbers compare technical specs without jumping between multiple tabs or brand websites. Whether you’re shopping for your first shoe or your fifth pair, this makes decision-making more straightforward.

3. Send-O-Meter™ Matching System
Our newly introduced Send-O-Meter assigns a match percentage to each shoe, visually showing how well it aligns with your foot shape, fit preferences, and climbing goals. While not every shoe will hit 100%, this tool helps you quickly spot which shoes deserve a try—and which ones may not be worth your time.
4. Save & Compare Functionality
You can now save your recommended shoes as image files with a single click. This makes it easy to revisit your top picks later, share them with friends, or bring them along when shopping in-store.

Under the Hood: Key Improvements in Senderella+
Enhanced Accuracy and Verified Specs
Every technical shoe detail—such as stiffness, volume, and curvature—has been re-verified with manufacturers. We’ve also added arch height to the volume category, offering a better sense of how shoes might feel on your foot. No more guessing whether “medium volume” actually means medium for you.

Smarter, More Adaptive Algorithm
The upgraded recommendation engine considers not just your gender, but also your:
- Foot width and arch
- Experience level
- Preferred climbing discipline (sport, bouldering, gym, trad)
- Fit preference (snug vs relaxed)
This refined matching system ensures you’re getting a recommendation based on actual compatibility—not just marketing labels.
Relatable Fit Guidance
Instead of relying purely on tech specs, we’ve rewritten our shoe property descriptions to reflect real-world experience. For instance, we now explain how climbers with wide feet typically experience pressure in standard shoes, helping users immediately recognize what to look for in a better-fitting model.
Designed to Guide, Not Decide
No tool can guarantee a perfect shoe on the first try—because no two feet (or climbs) are exactly alike. But Senderella+ bridges the gap between guessing and choosing wisely. Our goal is to make your search easier, help you understand the trade-offs, and give you a clearer sense of where to start.
If you’ve ever felt overwhelmed trying to choose between dozens of shoes, Senderella+ was made for you.

Building Senderella+ was a true community effort. Your feedback shaped every update—from the smarter algorithm to the added fit descriptions. We’re proud to offer this tool completely free, and we’ll continue refining it as more climbers use it and share their stories.
Climbing is personal. Finding your next pair of shoes should be too.
