want to get clip less pedals and cycling shoes for the first time for a sirrus sport. I also don't want to spend too much in case I don't like them. ANy suggestions out there as to what to start with?

Depends on what kind of riding you're doing.

I guess if I were riding a Sirrus in NYC, just getting into riding, I'd go with a mountain bike shoe and pedal.

Maybe take a look at Performance. I think they might have a couple of crank bros. pedals on sale for around $60. A lot of people like these. Check the coupon forum for a hot deal.

Next, figure out your cycling/walking ratio an select an appropriate shoe. Performance oriented mtb shoes are not pleasant to walk in while the most walkable shoes are not great for riding.

I went with Shimano SPD clipless pedals with MTB shoes. I just found them easier to walk in. Originally, I had the Shimano M-324 platform/clipless pedal. One side is platform for riding in normal shoes, the other is SPD compatible. Great first time pedal but I found that I never rode without being clipped in so I upgraded to Shimano M-520 pedals which are dual sided (and fairly inexpensive). I have Specialized MTB shoes.

Cheaper shoes tend to be soft which can contribute to hot spots and numbness, especially over long distances and especially with small cleats and pedals common on MTB systems. Some people, however, do fine with these setups. It depends on your feet. I use MTB style pedals with stiff-soled shoes.

I also ride a Sirrus in Manhattan +1 on the MTB shoes - especially if you ever have to carry your bike up several flights of open metal grated stairs to a bridge path.

specialized shoes are a pretty good value, especially if you can get a deal from the shop that sold you that Sirrus
