Another numb feet thread!!! LOL

Well... once again....this happened to me before and I also had the right shoe size on. BUt in the end.....it was a problem of shoes. I used Time road shoes. and they always made the same thing to my feet after a couple of miles.

Change your shoes (yep you are gona spend some more $) make sure you tell the guys on the store what problem you are having.

I recomend the Sidi T1´s.

Forgive me for asking the obvious question but are you sure you're not pulling the straps too tight? That's ususally the cause for my numb feet, especially with new shoes.

Try one or both of the following:
1. buy Specialized Body Geometry shoes. They have a little nubbin (I forget what they call it) in the ball of the foot that helps prevent numb feet. They are great shoes. I have friends who used to get numb feet with their shoes and switched to the specialized shoes and were fine. Here's info on this technology:
Body Geometry Shoe Design

Co-developed with Dr. Andy Pruitt, sports medicine expert and head of the U.S. Cycling Federation Sports Medicine program for four World Championships and the 1996 Olympic Games. For 2005 all our Shoes feature three revolutionary technologies to stabilize the cyclist's foot bed, help prevent injuries, and measurably increase performance.

Varus Wedge

The Varus wedge [A] slightly angles the forefoot to match its natural canted position, bringing the foot into full contact with the pedal and eliminating rotational movement of the knee, shin, and forefoot [B & C]. Compared to standard cycling shoes, the resulting movement of the leg during pedaling is smoother and better aligned, reducing knee pain and strain [D].

Metatarsal Button and Longitudinal Arch Support

The contours of the Body Geometry (BG) footbed support two key areas of the foot: the metatarsal button, and the longitudinal arch. The raised metatarsal button section [E] in the forefoot spreads the metatarsal bomes to prevent nerves and blood vessels from being crushed during pedaling, reducing "hot spots", foot swelling and discomfort.BR> The raised longitudinal arch support [F] provides a stable platform to minimize arch flex and improve power transfer and efficiency.

Proven Results

Physiology studies were conducted at the Boulder Center for Sports Medicine (BCSM) and presented in 2001 at the American College of Sports Medicine conference in May 2003. The study tested competitive cyclists riding at 80% of lactate threshold power for ninety minutes, followed by a progressive sprint to exhaustion at VO2 max. The same cyclists alternated between BG shoes and control shoes from another premiere manufacturer. The results were compiled and aggregated to form an overall picture of shoe performance.

The results of this study? At 60 minutes riding time with BG shoes, the cyclists' heartrates were still lower than after just 30 minutes with the control shoes. At 90 minutes, the BG difference was even more dramatic: heartrates with BG shoes increased almost 30% less over the final hour than when the same riders rode conventional shoes. And in the final sprint to exhaustion, cyclists lasted an average of 38 seconds-- more than half a minute-- longer at VO2 max when they wore BG shoes.

Net result: BG shoes not only improve pedaling efficiency, but measurably increase endurance in competitive cyclists. Just ask the BCSM.

2. Get pedals with a larger foot platform. Like many of the Look pedals or Shimano SPD-SL style.

also check your pedals. if they are not smooth, i.e. when the platform rotates around the spindle, if the action is not silky smooth, it can cause vibrations through your shoes that make your feet go numb and/or other foot pains.

this is in addition to the shoe responses above.

personally i ride Sidi T1s with Speedplay Zeros. i started as a mountain biker with shimano spd cleats, then switched to the Speedplay. i've been very happy with the Sidi/Speedplay combo on my bike. just remember to do your preventative maintenance.
