I paid a whopping $5 for my Specialized spd-equipped spin shoes at my LBS.

The left shoe was a size 38 (my big foot) and the right shoe was a 37. Sometimes, you can still find a steal at the old brick and mortar store...

If you don't need a super stiff sole, Nashbar has been running some shoes very cheap. I got my lady 2 different pair for $60.

I use a pair of Pearl Izumi Tri Fly IV's on the trainer. No specific reason other than to make my road cycling shoes last longer.

My 31 year old Retrotastic NOS eBay bargain for spin :



WD :-)

I used to use my previous pair of road shoes for spin classes and just switched to some Keene Commuter shoes (off of amazon they were on sale at the time), The big upside is that I can wear them to the gym (driving a stick no less). The convenience factor is nice since I can stop off at the rower before/after, etc. I can't run in them of course but it's nice to not haul around gear.

Any ancient shoe you can find on Ebay will do. I use a ~7 year old pair of Shimano M086s I think I got for $50. Actually, they're great MTB shoes and I use them on my fatbike now as well. Indestructible.
