Yup that could still work, however you'll need to get a ~$20 USD bluetooth adapter for it (like this one on Amazon). Let me know if you want me to send you the details on how to download the test app. Thanks!!

Your shoe is for an SPDSL or Speedplay pedals.

However, looks like a converter does exist; however I... wouldn't normally recommend something like this, but if it's a must: https://www.amazon.com/Wellgo-Cycling-Shimano-Adapter-Cleats/dp/B00E7UZHB6
